Notice: Experimenting with HN

412 points by pg ↗ HN
Over the next few weeks I'm going to be experimenting with some of the ideas discussed here

http://news.ycombinator.com/item?id=2403696

so don't freak out of the site changes in some way. It will probably change back.

I like the no comment scores, orange dot idea (which has made a comeback).

I hope it leads to less of the mob voting mentality which seems to take hold every so often in some of the more popular threads and less of the "Sorry I downvoted you" comments that appear every so often.

On the other hand, comment scores are a very quick and easy way to see what's popular, which is still normally an informative comment. Having to wade through a lot of highly voted comments may take a bit more effort but will expose people to a greater variety of opinions.

Well, consider me happy (though weirded out a little) with the lack of points on comments - in retrospect, I think a lot of my downvoting behavior has to do with what I think a post should have earned, not what I personally think about it, and that's probably bad.

OTOH, I'm in the habit of scanning for double-digit comments when I want to save a little time, so I miss that.

However, upvoting appears to be broken just at the moment.
Looks like it's fixed now.
What's the threshold for the dot? I guess that takes the place of my double-digit filter.
There are other comments about a 'dot' also. Am I missing something? I don't see any dots of any color (And I don't think I've ever seen any dots).

(comment deleted)
the dots were there 1 hour ago, pg changed it back.
They're gone again.
gone now
And your noob throwaway account is now highlighted in Green. Check out the Noob Stories page for more (or to see if it's already changed back) - http://news.ycombinator.com/noobstories
Before I saw this I had naively figured that the green highlight was supposed to represent something positive, like YC alumni accounts or something.
Makes it easier to see spammers, I noticed this morning.

Sometimes, I do the reverse of what you described. I upvote comments that are at -1 (even though I wouldn't have upvoted the comment if it hadn't been less than 1.)

In these cases, I have a neutral feeling about the comment, but upvote it because 0, -1 etc. seem unfair.

Hiding the points will mean that HN will lose some of its self-correcting capacity (when it comes to comments that were downvoted unfairly).

Anyway, it will be interesting to see the results of this experiment.

Yeah, I do that too, sometimes, especially when I feel like someone has been downmodded by mistake.
Downvoted comments' text is still in varying shades of gray though.
Actually, I think there is a flaw in not providing the number: You have no idea which comments are generating activity

When my number changes, I click threads and scan for a different number than I recall for my posts.

This tells me which ones are still being read.

If there was a visual indicator of posts that had the arrows ticked since I last looked - this would be solved.

Otherwise, it is akin to throwing your comments to the wind with no indicator of how each is received unless they get greyed out by down voting.

EDIT: I don't feel like I have any incentive to click the arrows on anything if I cant see the result of that click. This really really is a bad design choice.

At a minimum we should be able to see our own scores.

EDIT #2: Also, assuming two people reply to a questions asking for a recommendation for X with a link -- you have no idea what the crowd's opinion may be of the links without them replying.

Typically good content is VOTED UP as an indicator that it is, in fact, good content.

The more and more I think about not seeing content scores, the more obvious it is that this is just flat wrong to not show them.

I don't know. If I can't see the little score increment or decrement in response to my up/down vote, I find I have very little urge to actually click either button. With no visual feedback to tell me "Yes, that click actually changed something", where's the satisfaction in voting?
I've still seen points displayed on some comments. Is this a temporary glitch or is there some reason they'll be displayed sometimes?
Can no longer see even my own points. Don't think that's positive - I like the feedback over what comments I make that people like and which are less well received.
Yeah, I totally agree with that - I've gained 45 points in the last hour, but I don't know why. That's a big turnoff for me.
Solution: Hide your karma score :P
Problem: joy gone from life.
I would be okay if there were some way to tell roughly how many points a post was getting, even if it wasn't precise. For example, some sort of color coding that moved to warmer colors on a roughly logarithmic scale.
Yeah, I really miss being able to scan for high-point comments already. I've only spent about 15 minutes on HN with the new changes, and I've already basically started ignoring entire pages of comments because they'd take too long to sift through to find the insightful stuff.
high point things usually float to the top.
This is true for replies directly to the article, but replies to the comments turn everything into a huge mess. I liked being able to see at a glance whether the thread below a comment was worth reading as compared to the next comment.
On the other hand, you're saving time.
I fear I'll spend more time on HN reading every single comment. Good for the less well-known posters who don't get upvoted by reputation alone, but bad for me and my work. However, having observed and stated that fear, I can now work to counteract it should the post counts remain hidden.
What you find by scanning for high-point comments is not necessarily insightful stuff but rather, most upvoted stuff. Then you upvote it, making it feature even more prominently on the page. The comments that you didn't read, no matter how insightful, get no points from you so they fall further down the thread. I've seen this happen, joke comments positioned very high while truly good comments are very low because nobody had the patience to reach the bottom of the page, read them and vote.
Certainly. I understand what is happening. But either way, I don't have the time nor the desire to read every page of comments in its entirety, and I like having some kind of filter.
It seems that you can still see how many points a comment has when it's nonpositive.

Edit:

And there are other comments with negative points where the number doesn't show. And still other comments with positive score that are showing up. Consider me confused.

You can see points on your own posts (which is a good idea!) but not others, it appears.
I see that your post here currently has 1 point.
Maybe it's just switching around randomly for now? Because now I can see the points of both of your comments.
Like pg said:

"so don't freak out of the site changes in some way. It will probably change back."

The orange dots / hidden points change has probably been temporarily reverted, that's all.

We're not freaking out -- we're just curious why things are working the way they are.
Didn't mean to imply you were: I was suggesting that the change might have been temporarily reverted. Looks like it's back now.
I'm seeing green usernames for submissions and comments by new users (not sure exactly what the threshold for "newness" is, the person I saw created their account in the past hour)
Did they stop doing that already, or are we being A/B tested?
Still happening as far as I can see. Try /newest - there's more green showing there.
As I can see, every user with a submission on /noobstories is green, so that's probably the threshold.

Edit: On further inspection, it appears I'm wrong, there are users there who are not green. The newest users I could find that are not green created their accounts 6 days ago. Users who created their accounts 4 days ago are green. I haven't had any luck in finding users who created their accounts exactly 5 days ago. So the threshold is either 5 or 6 days.

I think using green usernames for 'noobstories' is wrong. Green is usually linked to positive behaviour, earned reputation/karma or a special (empowered) user status; not for indicating that a user is new.
Green is also used to connotate inexperience or lack of maturity, e.g. greenhorn, green lumber.
Okay, I'll come clean. I've been experimenting with HN for over three years.

At first, I would try out HN and the effect on me was quite mild. I simply didn't see what the fuss was about. But the most I experimented with HN, the more I realized how powerful it is.

Nowadays, I use HN daily, sometimes more than once daily.

Sure my relationships with people who don't use HN have suffered. But who cares? They don't understand. That's why they don't use HN.

This intrigues me. I don't get your comment. I thought it was going to be a joke about drugs or some church or something. Is this in response to the title 'Experimenting with HN'?
Neat - even though we can't see votes, downvoted comments are gray. Maybe all of a thread's comment's color will be normalized between Black and Invisible, depending on a comment's relative number of upvotes (or negative score).
(comment deleted)
Is there a way we can see the current list of changes that are in production? While things like new users being colored green are obvious, other things such as a change in the decay function on the front page may be less obvious. Just curious to see what's going on at any given time.
(comment deleted)
Maybe using the "top color" from the user's settings?
(comment deleted)
FWIW, my immediate gut reaction to the lack of comment scores was extremely positive.
So here's a problem -- I think we all know that up/downvotes are routinely used to agree/disagree with the comments. With one notable exception, which is when the comment sits at 1, in which case it is not likely to be downvoted in disagreement.

Take parent comment for example. I disagree with it and if it had a score of 2+ I would've downvoted it, because my gut reaction was not "extremely positive". Now however I look at it and do not know if it's 1 or 2+, and so I cannot cast my disagreement vote without potentially pushing the comment into non-positive range.

(edit) Actually... what if there was separate agree/disagree indicator for each comment. As in "I was going to say something, but this comment is exactly that -> agreed". This will turn up/downvoting back to its original role of interesting/junk quantifier.

I was always under the impression that voting is not to be used for agreeing or disagreeing, but rather to reward a good contribution to the discussion (and punish a bad one). I have on numerous occasions upvoted a comment even though I disagreed with it just because I think it has been valuable to the overall discussion.
That's the idea in theory. In practice, it's clear that upvotes/downvotes are often used to guide the discussion in the direction that the voter wants it to go, which is often towards his/her innate biases.
I think this ability to vote in two different ways would be extremely interesting.

The agree/disagree voting stated above would give people insight into what others personally think about their comment and possibly push people to ask themselves, "Is this a useful, interesting comment, but I don't like it because I fundamentally disagree with it? Or is this a bad (meaning - does not contribute or against rules) comment?"

If this system worked, some of the most interesting comments could be ones that are voted up a lot, but very disagreed with.

Although looking at it from the other side, I could say it would make it harder for new users to participate/get up to speed, voting types could be confused, and it would add another step to a somewhat complicated process. (Plus people just might not like it)

edit: Fixed grammar and clarified some of my ideas

A lot of people on HN, myself included, consider votes to signal contribution to the discussion and not agreement/disagreement. Your comment is right in that they are often used as such, but I don't think it's desirable.
Yeah, I know the guidelines, but pg himself said that using voting to express (dis)agreement was OK. I don't have a link to his comment, but it was mentioned in another thread few days ago. To me his position confirms that the voting function currently sits with one butt on two chairs, and this may be the root of the fanboy-style mass-upvoting problem with comments (that, again, was pointed out by pg not few days ago).
> but pg himself said that using voting to express (dis)agreement was OK

A link to his comment would be really appreciated. I find such statement, which is so contrary to guidelines, hard to believe with proof.

A quick search on http://searchyc.com/pg+disagreement gets me the following pg comments:

http://news.ycombinator.com/item?id=117171 "I think it's ok to use the up and down arrows to express agreement. Obviously the uparrows aren't only for applauding politeness, so it seems reasonable that the downarrows aren't only for booing rudeness." - pg, 1150 days ago

http://news.ycombinator.com/item?id=392347 "Downvoting has always been used to express disagreement." - pg, 852 days ago

http://news.ycombinator.com/item?id=658691 "IIRC we first had this conversation about a month after launch. Downvotes have always been used to express disagreement. Or more precisely, a negative score has: users seem not to downvote something they disagree with if it already has a sufficiently negative score." - pg, 665 days ago

Thanks. Not sure if I agree with PG's opinion though.
It would be good to provide a link. I've been through the last 8 days of pg's comments which you can browse here and haven't seen anything to that effect:

http://news.ycombinator.com/threads?id=pg

Discussions will end up quite boring if people use votes to agree or disagree rather than expressing their point of view in a reply. I tend to think of votes on HN similar to the options for moderation on Slashdot: vote up for insight, vote down for off-topic or flamebait.

It would be good to provide a link.

pg from 1150 days ago:

http://news.ycombinator.com/item?id=117171

I have had this bookmarked for more than a year, as this issue comes up over and over and over again. Sometimes downvotes to express disagreement with the stated position in a comment is the most concise way, the way most friendly to other readers of HN, to indicate that the comment didn't add value to the community.

Of course, pg is experimenting right now to see if different software settings make upvotes, downvotes, flags, and so forth have better or worse effects on the community as a whole and on particular threads.

Rather than keep trying to keep educating people that you don't want them to do what apparently is natural (I think digg and reddit et al have conditioned the upvote/downvote behavior upvote things based on agreement/disagreement/amusement.)

Maybe what's needed is to try an explicitly enable both these behaviors. Something like let the arrows become "popularity/reddit-mode" and add a separate "excellent" button next to "flag". Then you have two metrics without the annoying slashdot vectors. You can then either use the up/down votes or just leave them there as placebos.

I'm probably in the minority, but I actually like the concept of the slashdot-vectors as a way to give non-verbal feedback a bit more specific than "up" or "down".

The crux is of course in the choice of adjectives. I wonder what would happen if one would let the users choose free-form tags...

Free form tags, I assume, would move towards reddit/slashdot types of creative usage.

For example Slashdot current top article is: Headline: "Celebrating Yuri Gagarin's 1961 Flight Into Space" Author : "from the to-go-boldly dept"

This is the intent, isn't it? Force people to disagree by replying.
On the other hand, "disagree by replying" isn't always a good thing.

For instance, deliberate trolling is far better downvoted and ignored than engaged with directly. If a troll gets twelve replies going "Actually I disagree with your Hitler-was-great comment and here's a few reasons why..." then the troll has won.

Alternatively, a truly stupid opinion, even if honestly held rather than trollishly put forth, can derail a conversation. If every time the moon landing is mentioned it results in a big long conversation about whether it was faked or not (with the "yes" side argued by one random idiot) then that's not enhancing the discussion, it's just derailing it.

There are many issues on which sensible people may disagree, and many issues on which they may not. Sensible people should be able to figure out which are which, and downvote or reply accordingly.

PS. I think this comment is great, and I'm sad that I have no way of seeing whether anyone upvotes it or not.

(comment deleted)
My gut reaction was also positive, but then I realised I miss being able to see what comments the community finds valuable. Ordering within a thread as a measure of value only works if there are multiple child comments for a particular comment.

Sometimes people post long, multi-paragraph comments. Seeing a comment like that at 2 points makes me less inclined to read it than if it were at 30 points. Not being able to see points will make skimming comments slower.

Have you considered adding a slight cost for submitting articles? (perhaps 2-5 points of karma?) There's a reward for submitting anything first that other people are likely to submit, but no cost, so the new page is often clogged with industry buzz that drowns out more substantial submissions. Many excellent article fall off within an hour, and then they can't get reposted.

Having more articles on the front page that aren't based on a scramble for duplicate-submission karma would probably improve the overall discussion threads, too; those posts tend to draw a lot of shallow comments.

It would also help with spam. Win win win.

I also wonder what percentage of upvotes for submissions comes just from duplicate submissions - maybe those should be counted differently (or not at all)? If the front page is already full of threads about some news about Apple (or whatever), being first to submit a redundant (but distinct) post is disproportionately rewarded, yet reduces the signal/noise ratio even further.

The problem with this is it makes every submission into a karma game. If submitting costs karma, it will cause more people to think "will this earn enough points?" before submitting links.

... but that's not what you want people to think. You want them to think "is this interesting and on-topic for HN?" They're not the same question, as much as the former tries to approximate the latter.

If people focus too much on points, you're likely to get more groupthink and more industry buzz (since that stuff always gets a gazillion upvotes) instead of interesting articles.

Certainly, people think about link karma already, but I think this would make it worse. Creating a cost will cause even people who don't think about karma to think about it, even for just a moment -- which is probably not what you want.

I wonder about that, too, but think it'd be worth experimenting. The cost should probably be small.

I find myself wondering, "if I submit this now, will enough people be awake/etc. to notice it before it spills off the page?" That has deterred me from submitting more interesting content than costing 2 or 3 points ever would.

Also, a lot of those upvotes come from duplicate submissions. I don't have detailed info, but probably a significant percent, likely enough to lift them out of the new feed and onto the front page.

Or, maybe duplicate submissions shouldn't give the original an automatic upvote? I don't know.

Or, maybe duplicate submissions shouldn't give the original an automatic upvote?

Why shouldn't they? The fact that someone else indepedently thought the article was good to submit seems to be at least as strong a sign of interest as a click of an arror.

The problem here is that it doesn't distinguish between these two cases:

1. Multiple people independently submitted a content they found, because they found it interesting. This is (generally) good. Maybe it's not the community's cup of tea, and gradually fades away, but that's fine.

2. Somebody notices some fresh, overtly linkbait-ish article. They post it ASAP, hoping that fifty other people will be slower on the draw, netting them fifty upvotes. (Those people may be doing it for the same reason.) Either way: fluff gets submitted. Maybe it has fifty upvotes, maybe there are fifty others that just crowded out something really fascinating. This sets up a feedback loop that rewards posting things because they're linkbait, not thought-provoking.

I suspect that rewarding duplicate submissions too much tips the scales towards rewarding submitting linkbait. Looking at the new page basically ever backs this up. I don't know if adding a cost to submissions, reducing duplicate-submission karma, penalizing everybody involved for flagged->deleted articles, or what will help, but that seems like the root of the problem, so let's talk about it!

Interesting lottery-effect.
Even though it might not be the perfect way to estimate topicality for a comment/submission, karma is the best thing we have. As things are at the moment, groupthink is a huge problem no matter what rules you place on the system. You can't really stop it.

Everyone thinks about karma to some extent as it is, given that you can only do certain things with a certain amount of the stuff (downvoting, flagging, etc).

Even though it might not be the perfect way to estimate topicality for a comment/submission, karma is the best thing we have.

I don't think so. "Topicality" matches "lack of flagging", not "many upvotes". Or at least, it should -- there should be some standardized way, used by most HN members, of marking that they don't think a submission is good HN content.

This actually brings us to a very common problem on HN caused by the fact that you can't downvote links. It works like this:

Suppose you have two links, Link A and Link B. Link A is stupid TechCrunch linkbait, and Link B is an interesting scientific article. Link A is something everyone on the site understands, and 100 people upvote it. But in reality, suppose 2/3 of the people on HN actually would have downvoted it for being a terrible article -- but couldn't -- because there's no downvote.

Link B doesn't have as wide an appeal and gets only 20 upvotes, but nobody thinks it's a bad link. Yet despite 2/3 of the people on HN thinking that the TechCrunch article is terrible, Link A rates way higher than Link B.

While downvotes have their downsides, the fact that HN has no link downvotes basically guarantees that stupid linkbait industry buzz fills the top stories constantly. This is basically the HN equivalent of the Bikeshed problem.

It also gives people an incentive to submit the most linkbaity, overdramatized links possible, because the goal is not to submit good links: it's to submit links that get lots of upvotes. And when there's no downvotes, the best way to get upvotes is to get as much attention as humanly possible.

That's why i feel its best not to give any karma for submissions at all. karma only for comments.
That's a good idea, actually! Seeing a bunch of people discussing an article that you submitted should be sufficient reward in itself.
I second this. It baffles me when I see an article with 100+ karma and 5 comments. How can something be so interesting and yet spawn so little discussion? It makes no sense.
Not at all. I can see many instances where an "upvote" is a stamp of approval--almost like applause. Discussion is not always necessary.
As pg says, those are usually very good articles. I'd say the first impetus to comment is to correct, the second to add relevant detail. When the article doesn't need either, it's good.
Actually a high ratio of comments to upvotes is a bad sign. That usually means there's some kind of religious argument going on.
There are two types of articles that belong here on HN. The first type includes articles that speak for themselves. Everyone learns from them, but fell little need to comment unless they have something small to chime in. This type should have a low ratio of comments to upvotes.

However, the other type includes articles that provoke people and cause discussion. It doesn't just include contributing comments, but rather it contains debates and opposing opinions. These types of articles need a balance between a low and high ratio. However, the religious arguments you speak of are usually easy to find. These arguments are usually found in a deeply nested comment thread. Once you discard of fourth level comments and all the noise below, you should find that the ratio of comments is a pretty good signifier of the quality of the article.

It's very rare that there is a huge volume (>100 comments) of insight provoked by a single article, just because there's not usually that much insight to be had in the first place on that topic, and you can be sure that 100 separate comments didn't have it all on the same thread.

You usually can only get that much noise on a topic by poking people such that they NEED to correct some injustice done by the article. Sometimes good articles poke people like this, but in either case the comment thread ends up sucking.

I agree with you, but I'm failing to see how your comment is relevant to my suggestion.
If you don't think a story will get 2-5 up votes, then you probably shouldn't submit it.

And I assure you that people who don't think about karma (I couldn't care less) will continue to not think about it.

If you don't think a story will get 2-5 up votes, then you probably shouldn't submit it.

Unless a link is linkbait attention-whoring or breaking news, it's basically luck whether it gets that first upvote in its first few minutes to cause it to hit the front page. If you patrol "new" often, you'll see this constantly: tons of things in "new" are relevant articles, but still have no upvotes.

This problem only gets worse as HN grows in size.

Now, obviously, I have >4k karma and I shouldn't care at all about such a small karma cost. But the psychological effect exists regardless.

Adding to your comment, it could also encourage group-think: "I'll only submit what I know others find cool." Note: I'm saying this as someone who submits stuff I think is very cool but doesn't get voted up very often.
I'm pretty surprised by the amount of fundamental attribution error displayed in this thread.

If each of us is so confident of our own abilities to rate articles impartially, be objective, etc., why are we putting so much thought into how to ensure that we can keep each other objective? If I believe that I can do it, why can't I believe that you can do it too?

If each of us is so confident of our own abilities to rate articles impartially

Is anybody claiming this? I certainly am not. Quite the opposite.

I like the way this discussion is going. It is strange how karma could encourage people to act in a counter productive way.

1. How about not displaying the karma of new users for the first year?

2. The second insight is multiple postings from a news site. HN was good at recommending "hard to find" articles or esoterica. Where there are multiple people submitting the same link, it is probably not going to be hard to find or esoteric in the first place.

I don't get why a cumulative karma score even exists.

I like to see what other people think of my opinions and if I've touched a nerve. And I guess average comment score could conceivably be useful. But Total Karma just seems pointless. If the idea is to identify the oldtimers, then show their join date and be done with it.

It's probably an experiment in reputation. There was time when people would try to optimize their site's PageRank. The moment you start measuring things, magical emergent behaviors are created.
PageRank in theory relates to how well my site ranks. Does having high karma make my comments float to the top? Or show up in a bolder font?
Not as far as I know. You are free to ignore that number.
The point to cumulative karma is to feed the rodent-like portion of our brain which likes getting slow, semi-random rewards. There's a tiny amount of satisfaction you get every time you look at your karma score and see that it's gone up since last time you looked at it... and a tiny amount of disappointment every time you see it go down.
Exactly. It's the same basic principle that Farmville uses for more nefarious purposes. It's a method of encouraging participation and engagement, which makes it very effective for cultivating a community of like-minded individuals.
Timing can play such a critical role in an article gaining traction, that a lack of votes is not necessarily indicative of a lack of quality - e.g. right now, there is probably a worthy article on the new page that someone actively using no-procrast won't see because it is in competition with this announcement from PG.

Aside, I like not showing the points on articles.

>Aside, I like not showing the points on articles.

I'm actually surprised at how much I like not showing points at all. I generally pride myself on carefully considering people's arguments and voting accordingly (if at all), but I've found myself reading comments much more carefully. It's too soon to tell what the effect will be in aggregate, but I my initial reaction is to hope the change is permanent.

Crowdbooster is a YC company right? They should totally implement a feature for the best time to submit an HN article like they do currently do with the best time to tweet.

If you just polled new submissions and cataloged the number of upvotes over time, you could establish the best time to submit an article. If you want to get fancy, you could add some sort of categorization to the metric and break it down by category (like: "articles about node.js seem to get the most attention when submitted Tuesdays at 3:00pm")

The role of timing is interesting. It makes me wonder if a time-of-day-and-week based weighting could help out to reduce the need for posters to be so concerned about when they are posting.
But, uh, so what? Does something bad happen if your karma goes negative? That might be an issue. Otherwise, I don't get why people care.
What if the front page had a few random picks from the "new" page to give a little random extra exposure to undiscovered stories? They'd be different for each user...
You want them to think "is this interesting and on-topic for HN?"

My earlier proposal (http://news.ycombinator.com/item?id=2242453 ): deduct karma from submitter and _anyone who upvoted_ on submissions that were successfully flagged. That should get people to think the way you mention not only when submitting, but when upvoting as well.

Improve the submissions and comments will naturally improve -- submissions that are one-sided/gossipy/demagogic tend to attract similar comments. Whereas submissions full of technical content are often rich with links to further reading, contrasting viewpoints with cited evidence, etc. (Disclaimer: observations in this paragraph may be subject to fundamental attribution error).

I think there would need to be a little more to associate the action with the punishment. Since the point deduction would be pretty delayed from the voting, voters might not recognize which votes were poorly placed, and wouldn't learn to place better votes.
(comment deleted)
Hmm.

We might take this concept further and make it a "wager" of karma with a minimum bet, and you get gains at some rate proportionate to the size of the bet. But extending it in this way, it would probably also have to have some effect on the front page algorithm for a large bet to ever make sense. Which in turn could lead to a stagnation where elite posters are constantly sinking thousands of karma points into "sure things" and nobody else can compete.

Something to think about, in any case.

No, I think at most it should add just the right amount of friction.

Rewarding first submits is the real problem, IMHO. It's like, "first post!", except it also drowns out good submissions.

I think this would exacerbate the "comment quality" problem by encouraging people to make lots of sub-par comments so they can gain enough karma to submit their latest blog post.
Would it really help with spam though? The rewards for a spammer to make it to the first, second, or even third page are probably worth the risk of negative karma.

As for duplicate articles, I'm not even really sure what the problem is. Is it duplicate articles (same url, slightly different) that clog up the system? Or is it the same subject being covered from many different sources? There have also been a few times within the last month where two stories about the same topic will be right next to each other on the front page--amazon/apple/other big industry announcements like to do this.

Right, I have to imagine if I were a spammer, I would churn through new accounts fairly regularly anyway.

(Not to imply new accounts are always unwanted of spammy — we were all new once…)

I think most of the problem has to do with the fact that you are spreading upvotes and comments over two pages, rather then having them on one.
I expected that new accounts wouldn't be able to submit anything until they have a couple points of karma (from upvoted comments).

The problem is that the main page of the new feed frequently has a max age under an hour (44 min., currently) - if something doesn't get any upvotes by then, it falls off the page and becomes drastically less likely to get any further upvotes. It also can't be resubmitted for several months. Slowing this down would almost certainly be good - quite a few interesting posts get submitted at the wrong time and never get noticed.

There's a reverse problem too with complaining about karma farming eroding the SNR. I care about learning interesting things and couldn't care less about my karma on a website. I've only ever submitted two articles, and those were only after I read something that I found profoundly interesting that had just been posted (I read them right after getting an email alert that they were posted). For both, I also took the time to search HN to make sure they hadn't been submitted yet, before I hit the button. But the second one still drew complaints of being a duplicate based on prior submissions of a related previous Techchrunch post that hadn't shown up in my search and that I'd never noticed despite hitting HN several times a day, because they hadn't been upvoted at all and had quickly plummeted off the first few pages. I hope a solution can be found that cuts down on both redundant submissions and occupying comment space with annoying complaints about redundant submissions (and that obviates the need for annoying complaints about the annoying complaints).

I'd suggest trying just eliminating awarding karma to users, at least for submissions - just use the submissions' points for the ordering on the page. It takes way more effort to write a valuable comment than to hit submit for a link, so let comments become the sole determinant of users' karma. I think users would still submit pages they find particularly interesting for HN out of desire to share interesting things.

I don't care about karma either, but it's an arbitrary metric that steers community behavior somehow. May as well utilize that.
Overall I think eliminating the point display on comments works very well! I'm no longer tempted to pile on, either positive or negative, on comments.
The "green user names" might be nicer if it was a continuum -- that is, "newest possible" would be bright green, and it would fade to gray over the course of days or weeks.
You might just consider making the flagging ability more apparent, and give it to some of the more senior members of HN. I only recently discovered it, but it has been useful in removing posts that belong on Reddit.
8% of men are red-green colorblind.
I contributed late to the last thread - but having a monthly "Erlang Day" (not necessarily about Erlang) would help establish a baseline for the kind of culture we want while relying completely on informal methods, i.e. no changes to code or rules of the community.
Crossing my fingers that it will be easier to tell users apart soon. That's currently my biggest gripe.

EDIT: Aaand negative karma. I like the changes already.

I think it's good that the usernames don't show. Other HN members have expressed a similar opinion over the years... it prevents voting for/against the person keeping your impression of the comment (at least the first impression) based on the content and not the author.
Grudges are what Ignore features are for. (And the opposite for Buddy systems.)

I recently wounded up criticizing a start-up pitch in a thread, and it turned out that the person I had the conversation with was one of the founders. At least the OP - and preferably the coworkers - should be highlighted. The latter could be achieved by letting the OP include user names, when s/he creates a thread.

I strongly disagree. It's very useful to be able to qualify comments with what I know of that user, especially when I don't know much about the field being talked about.

I'm much more likely to take tptacek's advice on security more seriously than someone else's. Likewise with grellas's legal analysis, Patio11's small business/SEO advice, etc. That their names along might cause high karma for them isn't a bad thing. Quite the opposite, it causes their comments to be pushed to the top, which is almost always a good thing, as they're consistently the best comments in those threads.

It gives some measure of ability to gauge trustworthiness.

I'm not disagreeing. In fact, I upvoted you.

But I'm saying that the first impulse impression/reaction for a comment should be based on what it says, not who's doing the saying. After you read it, you can qualify it by its author. It's not like I'm suggesting we hide the author or anything - it's right there, when you need to find out who wrote what. But don't make it stick out any more than it already does. Put the content front and center, and make it the focus of attention. After you've read the comment and judged it for what it says and how its written, then reflect on who wrote it and what kind of weight that will give it.

Hacker News' display of usernames borders on anonymity; it's not highlighted nor emphasized in any way. It's like HN is an invitation to debate with its hivemind.

It should at the very least be easier to scan the usernames when reading large threads. Now, it's either a strain or something you forgo entirely. I'd be interested to see an eye movement analysis of HN users in relation to the username displays.

The red dot helps quickly identify comment threads that might be compelling (something I used score for before).. but the lack of scores on the comments view (using the 'comments' header link) makes that view almost useless to me.. I don't use it all that often, but occasionally peruse it to identify threads that may be more interesting than their titles led me to believe.
I really like having the flag button on the main page. My only suggestion would be to move it to the left of the comments button.

Either:

    points by user time ago | flag | 32 comments
    flag | points by user time ago | 32 comments
Otherwise it is too close to a commonly pressed button. Particularly on a touch screen.
I'm coming late to this conversation, as I was mostly internet free last week, but

a) Thanks for doing all this work b) I imagine you generally feel this way, but I would love to have changes err on the side of keeping the community small UNTIL it proves it can scale in culture and quality.

I say this having lived through the following community site's initial quality and esprit-de-corp rise and fall:

Kuro5hin, Slashdot, Digg, Reddit

Probably the only truly excellent community I was part of which did not have this problem was the Plato Network, but I expect it died before it could grow into many of the growth/quality problems HN or any of these popular sites face.

To my mind, the idea that one is required to grow beyond one's quality and community goals need not be true. Another way to say this is that if we graphed the ability of community websites to attract new members against their ability to maintain / improve quality and culture, so far that graph is significantly below the 1:1 line.

Creating technology to change that slope above 45 degrees would be a totally huge gift to the world, seriously. On the other hand, the best sites out there might be at less than 25 degrees right now, so even a little would be a big improvement.

All that to say, I'm all for experimenting, and I know for sure that you don't really want to start HN(^2); you'd rather keep using and feeding HN in the right way -- I always find a big goal / framework to be helpful, and I haven't heard you say much about what your longterm goals are here; since talk is cheap, take mine!

One additional thought I had here; based on this graph idea, it seems to me a useful thing to do would be to create some sort of way to get a handle on community on quality using metrics.

They would probably be terribly inaccurate metrics at first, but they would also provide a means for people to decide how to assess.

As a start, you could use people, for instance paying people on Mechanical Turk to evaluate a post and its comments for specified HN guidelines; these could be used as a first attempt to get a feel for how well a given day / week goes.

I was thinking the same thing, but maybe also using sentiment analysis or other NLP techniques. Even simple word count trends might yield some insight.

If we could get a dump of all the comments tagged with submission time that would be a nice starting point for people to throw their algorithms at.

I really like this idea; isn't that what the "comments" link does at the top?
Please fix downvoting. Even right now, there's a thread that I can my post be downvoted, and then my reply later that sets the record straight be upvoted. Apparently people here vote before informing themselves or reading the rest of the thread. Regardless, not being able to change a vote, especially if a simple misclick is made, is very, very frustrating.
Should I start flagging stories that I just don't like rather than only ones that strictly violate the rules?
Suggestion: the Rerun button allows veteran users to signal that an article has reached the front page before. Far from flagging the links for removal, the rerun button signifies that the content has a timeless quality.. it definitely isn’t news, but it is still worthwhile. A link that is getting both sufficient upvotes and rerun clicks is moved to the Reruns page, which would feature all manner of old chestnuts and stop them clogging up the front page.
I really don't think that duplicate content was ever a problem for HN. It's just not an issue.

The community has done a very good job of providing links to earlier discussions and has generally accepted that occasional repeats of old content are nothing to get worked up about and may even be desirable.

I agree. Though I'd like something to address duplicate submissions within a small window. Like the double front-page stories of bing's 30% market share...or the double ask-page entries on the new karma-less comments.
Can you please consider reversing the "xx comments" and "flag" links? I think everyone here is used to clicking the last link under a submission to go to the comments!
+1, please. I very nearly flagged some submissions; on a slower day, I wouldn't have even noticed.
Either reversed, or can we get the comment link up to the right end of the top line of the submission, so that I'm not forced into scanning over and navigating over the "flag" button on the way to reading the comments?
