Ask HN: Why do people write comments?

38 points by behnamoh ↗ HN
I'm genuinely curious as to why people leave comments on forums, reddit, HN, social media (YouTube, Instagram, etc.).

The problem is: Most comments will not be read by anyone (or read by only a few), so what's the point of expressing your thoughts and opinions through comments?

For example on HN, sometimes there are hundreds of comments on a post. HN doesn't notify you of replies to your comments. And yet, people write comments, maybe hoping that someone will reply to them. I just don't know what the "utility" is in these situations.

Is it just to get it out of your system? To document your own thoughts for your future reference? And how does that work? I believe if people want their comments to be seen, they may put them at the top, possibly in response to other comments (and sometimes it can be annoying when a reply has nothing to do with the parent).

And btw, what makes this even more surprising is that most social media, forums, HN posts, etc. have a short life time. What is the benefit of the comment you put on an Instagram post—that gets forgotten in a manner of seconds? Worse yet, IG doesn't even keep all your comments on your profile, so it's like writing on the walls of a city you're never going to visit again.

That's so true :) I think this world is absurd so the best one can do is contribute to the absurdness. Absurd is its own utility.
I like hearing different takes on a subject. People here come from all walks of life and are not all stereotypical basement dweller hackers. You claim that comments don't get that much attention, but they do. Some comments could even be likened to a blogpost, the only difference being you didn't setup a site, and people go here instead to read various takes on a matter. Also you mentioned that HN might go away some day, but I imagine it would be archived and go into read-only mode in that case.

Maybe I wasn't clear enough! I meant HN posts are temporary; they get out of the spotlight in a manner of hours (or a couple days). Plus, HN doesn't allow replying on comments of older posts.

Ah gotcha. Well sometimes posts re-surface after many years as HN allows for that. I've often posted something that was on HN ten years ago, and have a whole new discussion, even if the URL hasn't changed! Some posts are given a second chance and are not deemed a 'dupe'.
Why do people have conversations in real life?
In convos, you know the other person hears you and can respond. But when you comment under a post with 900 comments, yours is probably not going to be seen and responded to. How many people scroll all the way to the end of comment sections to read all comments?
I do that, depending on the topic. Because I know that there will be some people who are late to the party with good comments.
Its not a 1-1 conversation, its a group conversation. Not all group comments stick and end up as the next random discussion, but that doesn't mean they weren't heard (read). Sometimes someone says something and the conversation can just continue without a full comment in return.

And how many posts have 900 comments? Even the heavy traffic posts I see rarely approach those numbers usually we're talking 100-300.

I love reading comments. You never know when someone will enlighten you with a different perspective on something you've thought you understood well forever. As well as the joy of having people who understand things that I do not, explain them to me in a casual way. The chance of having someone share their joy is much higher than in more formal writing contexts.

I write comments not for the ages, or for the engagement, I want to share my perspective in the hopes that it will give others the same joy I've received from their comments.

How many published books actually get widely read? I mean, if you're uncomfortable throwing your words out on the net, then what forum is worthy of your work? Why publish anything if it won't be forced into the minds of every schoolchild by government backed indoctrination systems?

If you think of yourself as a writer, if you think written communication is important, even; what better opportunity to practice the craft? Would you respect a musician who never took up their instrument unless there was a large attentive audience? Or is it still worthy to play the trombone out on the back lot for no one but yourself and the cows?

this as well as indexing by search engines, i found some wonderful perspectives about rails for example from hn comments, things which were much better than any seo optimized content that you find now.
Can't speak for others but I find it nice to exchange thoughts with fellow humans (or AIs) (or dogs).
"Come for the article, stay for the comments"

If I leave a comment, it's because I feel it might be useful/interesting to the topic being discussed. It's also nice to read similar experiences from other commenters and there are nearly always some handy links that take me off on a whole new Internet journey (a bit like catacombs). QED!

It's nice to read that! I know what you mean. At the same time, I think there's always gonna be an overlap in comments because you might share your perspective whereas someone else (whose comment you didn't read) has already written a similar comment.
People will read this comment.
People will upvote this comment.
People will downvote this comment as it s about butterflies.
People will comment on you're grammatical mistake.
People will comment on the relevance of your username to the content of your comment.
People always underestimate the amount of readers in any place where you can leave comments. The great majority doesn't even upvote/downvote, and a small percent actually leaves comments. Check any popular site who tracks views, like Twitter or YouTube. Thousands of views, hundreds of votes, tens of comments.

In a high-traffic site it's almost guaranteed that at least one lost soul will read you comment, maybe vote/flag it, and maybe maybe reply to it.

Even if I can accurately estimate the # of replies I can expect, still the question could be asked - why comment?

But like you said, someone sometimes replies and you get pulled into threads like this - which is somehow way too much fun lol - so agree about commenting to start/participate in such convos.

Personally, more often than commenting, I forward the articles I know will be interesting to people in different group chats. And there is a lot more back-and-forth there.

People will love this comment.
When I comment on an old thread on HN, it's probably because I haven't noticed that it's old, because I agree there's not much point commenting on a thread where your comment is unlikely to be read by anyone.

On Reddit, where threads seem to hang around for longer, I might comment on an older thread if I think my response will be helpful to others, but not just to voice my opinions.

Because I feel like I have something to add to the conversation. A data point, a related story, a rebuttal, a joke (on reddit), etc. I often find comments to be as good or better than the content they are about (If and only if it's a well moderated subreddit or HN) so when I can contribute I like to do so. Seeing people's different takes forces me to think more about an article/blog post than I otherwise would and sometimes challenges my own "beliefs"/thoughts which I think is a good thing.

As for HN replies I think a lot of people use a service like this: https://www.hnreplies.com/ to get notified, it's what I use.

Sometimes it does feel like screaming (or whispering) into the void if it's a post with a ton of comments on it already, though often if there are that many comments then my viewpoint is already represented so I just upvote that instead or expand on it if I have something to add. Rarely will I post a top-level comment if the thread (on HN or Reddit) is already large since I know it will get lost in the shuffle.

You say posts have a short life and that's kind of true but not always. It's less the case with Hacker News (though I do enjoy perusing the "previous discussions" of a link that's reposted years later) but Reddit (rightfully) comes in most search search results for things I'm looking for. The top example being video games for me. I can't tell you how many 7-10+ year old threads I've read to find answers to the questions I have. I've even commented on some of those "ancient" threads to give an update or "how it works today" for the next person that finds that post via search/google. Not all content is evergreen but a lot of it is. Home improvement, cooking, and city-specific questions are some more examples of things I've found years after the fact on Reddit that were exactly what I was looking for.

Why did you post this question? It will certainly have a short lifetime.

If a person knew their comment would definitely never be seen, it's probable most people wouldn't write them. But on most sites, people are notified about new comments, and even here, it's possible to look at your own comment history and see replies long after the fact.

People post comments because they have questions and hope for answers--as you did with this post--or because they have comments and hope someone reads them and finds value in them. Same as any other form of communication.

Why do people speak to each other at dinner? Not a rhetorical question...

I like to read comments just to see another perspective. I write comments to give my thoughts. Sometimes writing them down makes you recheck your own opinions and you think more about a topic.

Of course sometimes I also write comments because I am angry at the internet and the internet has to know.

It's fun to participate in discussions, although I rarely argue opinions, because what's the point? I appreciate all of the commentary on forums because, personally, I read lots of it. Especially when I'm trying to gather information on a product or similar.

> Most comments will not be read by anyone (or read by only a few)

That is a non-trivial distinction. It's the difference between talking to one person (or a few people) and talking to yourself.

> HN doesn't notify you of replies to your comments

No, but hn-replies does (http://hnreplies.com/)

> most social media, forums, HN posts, etc. have a short life time

So does the information exchanged in a face-to-face conversation. But face-to-face conversations have value. Comment exchanges are the 21st-century version of a casual conversation.

I actually prefer that HN doesn't notify on replies. It takes some time getting used to it, but it dampens reflexive replies, and that's an advantage I can appreciate better after a while.
Sometimes I write comments just to "get it out of my system". If the topic is something I wanted to work out in my mind anyway, it's a low-effort way to do that.

Sometimes I comment because happen to know a lot about the topic or can add something useful or insightful that isn't common knowledge, but that is not that often.

Some people are chasing "internet points." I see the allure and understand why it works.

Over the years, I've gotten more selective about commenting. I've mostly grown out of commenting just because "someone is wrong on the internet" and I will usually skip commenting if the thread is old and no one will see my comment anyway.

I'll never comment on popular FB/Instagram/etc posts where the comments are read-only trash and there's no chance of being heard.

I get a warm feeling when the number beside my comment goes up.

I read comments to perfect my own reasoning, thinking, and understanding of the world and others. Likewise, I write comments to sharpen my own thinking and have it tested by others. In addition, I contribute facts and observations that hopefully will lead to opportunities for others to contribute their own thinking and the loop can continue endlessly.

Hacker News is really the only forum outside of IRC where I bother to do this these days. I am also somewhat perplexed as to why you frame writing comments as wanting exposure and permanence. All I want is brief exposure to peers whose opinions I respect and whose feedback I can rely on. I get that here, but pretty much nowhere else. Permanence is manifested in the gradual betterment of my mind; my comments are but a means to an end.

For the same reason we launched Voyager, buried a time capsule, scrawled an obscenity on a park bench, or tossed a bottled message into the ocean. Amongst all of God's creatures, only man is dumb or spiritual enough to commune with oblivion.

It's just normal human nature and a desire of wanting to communicate with others.

On the internet comments are the mean of communication as part of an online community. That is no different to talking to a bunch of friends in the pub. It's like asking "why do people talk to each other in a pub. Most conversations in pubs will not be heard by almost everybody in the world. Conversations with one person are only ever heard by one person, so what's the point of talking to them and expressing your thoughts and opinions?"

Do you see what I mean? There is no point in the same sense as there is no point in life if that is what you think.

Because some people only or mostly read comments. Like me. Usually there a few posts giving more insights than the article itself.
Based on the number of replies I get telling me how wrong I am, I’m pretty sure that people do read my comments :-)
Because interacting with smart people is enjoyable. I only comment here, and I really like the community around this site. Smart people (or just people who think they're smart) providing opinions is a good way to expand my horizons.
