Ask HN: I miss Usenet. Are there any modern equivalents?

261 points by mr_gibbins ↗ HN
Much as the title says, I really miss the Usenet days where I could contribute to a bulletin board-style forum on hyper-specific subjects.

If I remember my computing history correctly, Google ended up acquiring and eating Usenet, becoming Google Groups. I'm not sure if this is dead yet.

Arguably, Reddit fills some of this niche, but Usenet was tech-focused, generally quite professional and frankly didn't have the same clientele as Reddit does.

HN is topic-focused, rather than subject-focused.

Would be very interested to see if there's any Usenet-style project that's still alive.

You can still access USENET if you have an account on <https://www.eternal-september.org/>. <https://news.individual.net> works, too, but I think it costs ten euros a year.
At least eternal-september and nntp.aioe.org are free access -- but both have text only newsgroups, no binaries groups.
There's a reason for that. Binaries groups were historically dens of piracy and CSAM. They consume HUGE amounts of traffic and hosting them presents liability issues to the providers.
Usenet binary groups still exist and are heavily used for piracy.
> dens of piracy and CSAM

Tangential, but fascinating that we've binned these categories together. The latter is likely orders of magnitude more harmful to society.

Indeed, but I was just listing them as "two major illegal things that binaries newsgroups are used for", not tie them together or relate them in a jejune "four horsemen of the infocalypse" kind of way.
I'd argue that piracy is beneficial to society. Copyright (and most of IP-law) is a scam at this point. 10y is enough on any IP-thingy (to have a head start on the rest of the market); but that's just my opinion.

Yeah looking at you Mickey Mouse.

The former's arguably net-beneficial, in a world with effectively eternal copyright terms. It's shouldn't be possible for Disney to own so much of the last ~100 years of popular media, for example, because most of that should no longer be ownable.
It's not about "harmful to society" in this case, but more "illegal, attracting attention from entities that make hosting the service much more painful and difficult".

More than once, I've had thoughts about developing some sort of discussion platform, but binned it because the thought of hosting it and having to deal with the not-fun problems of reducing spam and handling illegal content made it entirely untasteful. At least spam reduction can be done entirely on my own terms, but illegal content requires me to then coordinate with external companies or agencies, report content, figure out how to deal with and purge the content (or quarantine and hang onto it hand it over when requested), and live with the the pain of having to field DLNAs and other copyright claims.

I obviously have different feelings about piracy than I do about CSAM, but from a hosting perspective, both are just big pain points that make hosting a service where people can share non-text content a pain in the ass.

It sounds like that would be fine with the OP who is looking for tech community and discussion.
I think people overlook web forums. I would point to

https://coderanch.com/

https://www.dpreview.com/forums

and

https://polyamory.com/

as good examples. There are a lot of dead forums out there, but there are also ones where the administrators make the effort to greet new users and make them feel welcome. For instance that last forum covers a fraught issue where emotions run pretty high but the administrators do a good job of "onboarding" new users.

This is true. I have tried to maintain the same type of "great people" in my forum. It's a lot of hard work and it's been costly to maintain over the years. It is also admittedly very limited in focus.
> Arguably, Reddit fills some of this niche, but Usenet was tech-focused, generally quite professional and frankly didn't have the same clientele as Reddit does

I see you didn't hang out in alt.wesley.crusher.die.die.die much

Or anything in the alt or rec hierarchies really.
alt.religion.scientology is where many of the secrets around Xenu, etc., were originally leaked.

Not all of the alt.* hierarchy was vapid.

Yep, alt.religion.scientology, alt.tv.northern-exp, and news.admin.net-abuse.email were my main hangouts.
My first thought when seeing "tech-focused" was "let's see, I hung out in alt.atheism... wait, that's like /r/atheism?" (I see there's also an /r/nonsequitur/, kinda like alt.non.sequitur though the reddit version seems a more....attached to reality.)
Didn't alt.barney.die.die.die.die have more dies? I don't remember exactly

Usenet was a cost to ISPs unfortunately. But, it wasn't centrally controlled or moderated either. It also was minimally technical to use, which served as a good filter.

But I guess reddit's subreddits may be the best alternative with viewership and specific groups/areas.

You know... it should be possible with tagging to take something like twitter reddit, and generate "views" that are groups. Maybe make some spec with three letters, maybe R and an S, and heck another S for the hell of it.

Balkanization and content gardens/API walls block integration of like minded content.

The cost to ISPs was mostly in the binaries groups, and some usenet servers were set up as a paid service for this purpose when ISPs started dropping the binaries groups.

I don't blame the ISPs for this. At the time, you could be an ISP with what is essentially a low-end home Internet connection now, but it cost thousands per month.

What started the downfall of Usenet was Eternal September when AOL let their hoi polloi access the Big Boy Internet. The "Me-tooer" phenomenon was particularly irritating.

> What started the downfall of Usenet was Eternal September

that, and the unfortunate but probably not unexpected flood of actual child abuse photos. this became a huge problem real fast. an ISP I worked for back in that day dropped NNTP like a hot potato when the company lawyers caught wind of the potential legal issues.

Reddit is not an alternative as it is heavily censored (same as HN really) and centralized. Usenet still exists and discussions still take place there. Being a decentralized protocol, censoring (or scoring, killfiling) someone is left up to you.

And this is the major advantage of Usenet. You can’t be silenced by a mob, which leads to freedom of expression and disparate views. Sure there is spam and flames, but one gets all the tools one needs to deal with that. There is no committee deciding what posts should be kept or deleted. We are a lot worse off today than we used to be, largely because of the centralization of discourse.

> Sure there is spam and flames, but one gets all the tools one needs to deal with that.

Asking the user to implement measures and keep them up-to-date is detrimental to adoption from users that are aware of curated sources. Pretending this is net-neutral is misleading.

> We are a lot worse off today than we used to be, largely because of the centralization of discourse.

Usenet was centralized in practice, so I think you mean something else. It's not clear how much the curation of content stifles discourse when creating new forums is essentially free. Either way, I would tend to disagree that curated is worse. Everyone curates to some degree, even when they are free and open discussions.

Usenet is just better in this respect. Nobody says anybody has to use it.
Usenet was not driven by advertising, so it wasn't constantly pushing "click bait" and other unsolicited nefarious content onto its users. You could spew all the dumb misinformation you wanted to in your newsgroup, and it wouldn't leak into the more sane newsgroups (unless someone crossposted).
Unless you mentioned Turkey, in which case your group would suddenly see massive cross-posting by Serdar Argic.
You're thinking of the ".word.word.word" convention for newsgroup names. The last word would be repeated three times. The prototype for this was "alt.swedish.chef.bork.bork.bork," though "alt.wesley.crusher.die.die.die" (and the related "alt.ensign.wesley.die.die.die") came soon thereafter.

The name of the group you're thinking of was probably something like "alt.dinosaurs.barney.die.die.die."

rec.music.gdead was one of the most active usenet groups. IIRC rec.arts.books.sf-lovers was also a very popular group. I'm a bit nebulous on whether it originated from the mailing list or the other way around

There were also quite a few "for sale" type groups, I remember when the group for computer equipment was split into about five subgroups after it got too big.

Just editing to add - there were also a lot of regional groups, one of the earliest and probably biggest was ba.* There were also state/country level top levels and a few colleges had their own too

> Arguably, Reddit fills some of this niche, but Usenet was tech-focused, generally quite professional and frankly didn't have the same clientele as Reddit does.

It all depends on the community you want to hang out in. Usenet was tech-focused because the only people who knew about it or had access were tech-focused and the community was smaller (see: Eternal September).

One of your best options are niche, smaller or heavily moderated reddit communities or web forums that share the same characteristics.

The question is - What are you missing? I suspect you probably miss something that has more to do with the participants.

In the early days of Usenet there were very few ways to access it from the perspective of an average person. You either had to be working on one of the small number of companies that were internet connected or were at a university. That significantly restricted the available pool of people using it, and also filtered that pool.

Up through the early 90s that natural filter mechanism kept the focus of individual groups small, reduced noise, and increased signal. Over time as internet access became more widespread that signal to noise decreased, and most modern forums still have difficulty with it.

There are a few other interesting characteristics - the specific nature of the tree approach and the availability of lots of specific groups gave it some uniqueness - Today you might see a bit of that in Reddit subs, Facebook groups, and other similar platforms, albeit lacking the tree.

Piggy-backing off of this post: the answer is to get off the high-trafficked parts of the public internet. Examples:

1. Meatspace user groups / interest groups.

2. University lecture series (the type of weekly seminar that all graduate students and faculty in a given research area attend). You can usually attend as a member of the public if you have an "in".

3. Mailing lists and discord servers for specific projects.

"Moving Castles" was the terminology I heard someone propose[0].

Unfortunately they got too caught up in the crypto nonsense but the idea was sound - good communities have to be guarded and they occasionally "lower the drawbridge" to bring on newcomers, potentially with semi-public spaces. This could be a minecraft server, a facebook group or what have you.

Since the group is motile, they aren't affected by platforms being subpar. They can avoid stagnation by bringing in newcomers, but have a way to vet incoming people too before allowing them "internal" access.

[0]: https://trust.support/feed/moving-castles

Yeah exactly. Usenet wasn't what it was because of the technology, it was because the participants were mostly there to have 'professional' conversations, and the kinds of conversations that nerdy techie-minded people have over beers after work (wesley.crusher.die.die.die, etc).
As another Member of the Society to Reduce Wesley into a Little Styrofoam Dodecahedron, I can certainly attest that usenet wasn't as gleamingly professional as we remember. The original stereotypes of discussion group users (trolls, white knights, etc.) came from usenet.
don't forget porn, there was a tremendous amount of porn on usenet. a friend of mine had some perl script he called "aub" that scraped alt.user.binaries or something like that. catalogs and catalogs of stuff on a quiet little server in a university lab.
alt.binaries.pictures.erotica FTW

(There was also a computer at MIT called "zurich.ai.mit.edu" that you could FTP to in 1990 and download really raunchy NSFL porn. I still have scars.)

You mention the filter effect: I think what really killed Usenet, at least for me, was spam, much of which was automated, with no great mechanism in place to combat it.
These days you could fight spam simply by adding a proof-of-work requirement for posting content to the network. Isn't that exactly what this Web3/Blockchain fad is all about anyway?
This is a really interesting use-case. I don’t think posting spam is really a zero-cost thing though. So we wouldn’t be adding a cost, we would be increasing it. So I guess the big question is, how much can we charge per post that spammers couldn’t afford but wouldn’t scare away actual community members?
I think making a non-free Usenet is pretty much anathema to the whole concept of Usenet.
I wouldn't want to pay Real Money for it, but somehow it doesn't seem the same to say "I'll spend some finite amount of computation time/energy to make this comment". That seems like a much lower hurdle.

At the same time, paying ten cents to make a comment on Reddit or HN is very unappealing.

10c of crypto mining is about 30 minutes on an RTX 3090. It would have to be a much, much lower cost!
Wouldn't proof of stake be much more promising?

1) Start off with a trusted group of people (stakeholders)

2) Set up an invite-only system

3) Inviting someone means sharing some stake (i.e. some reputation) with them

4) To post you need some minimum amount of stake

5) With every post that's not downvoted into oblivion you increase your stake until you reach a certain equilibrium point. (So there's a limit and it's not about gaining status points.)

6) Posts that are downvoted into oblivion will cause their authors to lose some stake.

This is the best explanation of proof-of-stake I've seen yet! Thank you! This does sound just like minimum karma limits to me though. Per-community karma though instead of the global kind that Reddit uses.
>These days

HashCash is older than Bitcoin, and Bitcoin sybil-attack protection is basically HashCash.

From late 1990 until around 1997 I had a full feed via UUNET and ran cnews locally on my pc with cnews and trn for reading. It wasn't long before I had to scale back and drop all the binary groups and eventually others. IIRC a full feed when I started was about 3MB a day (still tough to do at 12/2400 bps)
I had a Usenet portal subscription between 2005-2008. I ran Thoth (usenet client) on Ubuntu on old Mac G4 towers. At the time, the connection speed blew away torrents.
It still does. I download 30GB 4k movies in a minute or so, consistently, from Usenet.
I missed torrentZ, do you know how should I search torrents again?
The thing I miss most was having one single newsreader interface that I could configure as I liked. With web forums everybody has their own idea of how things should work and I end up having to remember a dozen different flavors of "markdown" and ways of filtering users or threading posts. The Usenet had issues, chiefly the lack of a good way to moderate channels, but I wish we had gone with an open data model instead of the countless walled gardens that sprang up in its place.
Maybe matrix and/or mastodon?
I thought Matrix was more of an IRC replacement than a new Usenet. Mastadon always seemed to want to be Twitter.
Not quite IMO. Matrix gets very cluttery very quickly once you join more than a handful of rooms with lots of activity. At least with the mainstream clients. It seems more targeted at replacing telegram and its public groups than IRC.

The channel list in particular is way too low density.

Yea, that is something I too can appreciate. The simplicity of having a single place where I can read about a wide arrangement of hobbies, interests, and professions.
Not OP but the thing I miss the most from Usenet and IRC is the fact that they were client agnostic. I hate the discord client. I hate the reddit client and the facebook. I'd love to be able to have an open source desktop based client that I can modify and implement all sorts of plugins for it. I hate that we moved from services/protocols to closed vertical monolith.
I'm guessing they have limited functionality, but Pidgin is free software and has both discord and Facebook plugins. They've certainly made it difficult for the free software clients, but people continue trying to maintain this ideal.
> What are you missing?

Early Usenet was like Reddit, without the corporate (and come on, blatantly left-leaning) censorship.

Try posting on any of the right leaning subreddits, they are heavily censored and non-conforming people are frequently banned.

I’d encourage you to post a scientific or academic survey of Reddit’s political censorship. I think it’s common that everyone believes their own ideology gets censored when it’s probably not the case overall.

discord /s

every specialized sub-group now holds small portion of the web by/for themselves and only needs to interact with those of same mindset — no need to keep every single word in public forever.

but what you really missing is people of the same~ish age-group having enough time and topics to argue about

I think you can find the same vibe in Reddit, some forums and some mailing lists.

Also, HN not being subject focused works for me because I am interested in more than one subject.

One idea is if HN would introduce some tags, or categories so someone can filter if he's only interested in one subject.

Usenet is still there, I download TV shows from it all the time. The discussion forums are still there, too, but are completely overridden with spam. Most of the public unix [0][1][2] servers have a Usenet server that federates with some other tilde servers, though not the wider usenet. I stumbled across a group called ALTEXXANET [3] that claims to have one, though I've not checked to see if it's still there.

What were some of the newsgroups you were interested in? When and why did you stop checking them?

[0] http://sdf.org/ [1] https://tildeverse.org/ [2] https://tilde.club/wiki/usenet-news.html [3] http://www.altexxanet.org/usenet.html

A friend was still using it for tv/movie download a couple years ago too
I use a feed with no binaries groups, which is how I like it. Most groups aren't exactly overrun with spam, they're just not very active. One or two spam messages a day looks like a lot when actual users are only posting one or two messages a week. But if a group is active (like comp.sys.raspberry-pi), you hardly notice the spam.
HackerNews seems a viable alternative with a daily delivery of interesting topics, excellent moderators and often highly interesting comments from a diverse crowd of users -> check it out ;-)
I never thought of usenet as tech focused. There were many areas that were non-tech topics. Sure there was comp.sys., but all the alt. boards and others. Web forums were kind of the spirtual successor, and many of them have subject subforums, but within that most web forums segregate discussion by thread. I find that much more useful since usenet felt like a mailing list of post after post after post. Threads allow me to ignore discussion that aren't relevant to me.

I haven't migrated from web foums to reddit or facebook groups though I'm sure there is much information in those places. I prefer that independent web forums introduce some friction to participating. You have to create an account, and some forums have limits for new members until they reach a certain post count. While the friction is small that does seem to discourage bad behavior a little.

I have easily found forums for subjects I'm interested in, but none of them are tech, so I don't know whether you'll find web forums on current tech subjects.

> If I remember my computing history correctly, Google ended up acquiring and eating Usenet, becoming Google Groups.

Usenet was a distributed set of news peering relationships, exchanging posts via NNTP. There was nothing to acquire, so that's not what happened.

Google merely set up a web interface to it, which was eventually extended to the abomination that was Google Groups. This was intended to be some sort of mix of Usenet group and mailing list, all via a web interface. In reality it was awful and I suspect development on it stopped 10+ years ago.

Dejanews built that frontend on top of an archive they had. Google bought Dejanews and thus the archive.
Google really destroyed that archive, there's posts from the 80s and 90s I know used to be in deja and in early google that just can't be found any more.
And it seems that a lot of uuencoded content was removed at some point. You can see the text of the message, but the uuencoded part is mostly cut out. Here's an example: https://groups.google.com/g/misc.int-property/c/f2-dV5wVP9U/...

If anyone here knows how to get the uuencoded part of that message, I'd be interested.

You can't. It was never there.

I wrote the first custom NNTP client for Deja. (This was a high-performance replacement for the community, open source client.) All it did was receive and dump articles in a format for the indexer. It did some light processing, including stripping uuencode content. So uuencode never even made it into the archive.

Thanks for the information. I figured someone here might know something.
Agreed. I posted a lot in the 90s, especially to groups like sci.math and rec.arts.books.tolkien, and there is almost no trace of any of it in Google groups.

When Google bought the Dejanews archives I thought it was good, because Google was good at search and I naively still believed that the company actually wanted to make all information accessible. It's a real shame that all of the old Usenet stuff is gone.

To be honest a lot of what I posted back then I'm happy has been lost to the sands of time.

I will say one thing I've found strange is how spotty old posts are. Even within the same newsgroup. I can easily track down old posts of mine but sometimes stuff is spotty within a single thread. I've not seen any true rhyme or reason to what's gone and what remains.

The final nail in Usenet's coffin was the removal of the discussion filter from Google searches in 2014. Before that, people could use that filter to easily find others talking about something, but apparently that didn't please advertisers who wanted users to find only companies selling that something, so Google removed that filter and problem solved.

https://www.seroundtable.com/google-discussion-search-dead-1...

https://browsermedia.agency/blog/google-kills-discussion-sea...

Google acquired DejaNews, which was a popular web interface for reading Usenet. They rebranded it into Groups at some point.

But what is called Groups now is something else entirely, as you said.

Google Groups still has usenet support, I used it the other day trying to track down the source of an old story.
> The abomination that was Google Groups

FYI, Google Groups are literally the “groups” of Google Workspace — every time you create a group of users to e.g. assign that group some GCP roles, that group then also gets an email address (that being the group’s global primary key), and that email address then implicitly becomes a mailing list all group members are subscribed to.

It’s actually very useful in a corporate Google Workspace context — it’s rare to need an actual mailing list given Slack et al, but they’re effectively “group email-forwarding aliases”, allowing messages to e.g. devops-billing@example.com to arrive in the inboxes of multiple people.

the fact that it's a mailing list is so much better than a plain forwarding alias: it's a searchable/shareable archive for people who joined later. No more asking a coworker to dig through their emails for some important information
The gateway between Google Groups and certain newsgroups is still running, in both directions. For example, I received a copy of this Groups posting https://groups.google.com/g/de.soc.recht.steuern+buchfuehrun... over regular Usenet NNTP.

The technology is still up and running. Some of the people from the 90s are still there. But Usenet definitely has peaked in terms of users and postings.

… [166/256] GIANT FILE… [167/256] GIANT FILE… [169/256] GIANT FILE… …

Kids today will never know the pain.

"GIANT FILE" == porn...

How many of us attempted to automate this process :-)

That's what parity data was for. There were even clients that would seek out all of the binaries that had enough parts for a full download and do all of the work for you.

That said, alt.binaries was a big reason that ISPs started dropping Usenet. The other being the ever decreasing signal to noise ratio as the entire system proved to be vulnerable to spam and trolls. Yet another example of why moderation is a necessary evil if you want to scale up a discussion group.

The solution to that was a perl script called (I think) aub (Assemble USENET binaries). I remember back in the 90s, some friends and I in college would run that as a cron job to accumulate files over time. This was long enough ago that the version we ran was Perl 4.
(comment deleted)
This is interesting, i know that same script. I thought a buddy of mine out of Arlington TX wrote it around '96 or '97. I didn't know it existed outside of our autonomous vehicle systems lab. We used it to accumulate and categorize certain pictures.
Take a look at https://lemmy.ml/ . It's a federated reddit alternative that has a very usenet-like feeling. You can also go for one of the other instances (there are some good ones like feddit.de and also some really crazy ones).
cool technology, not enough people.

which can be said about usenet too lol

like, even fedi/ration with mastodon &co is not enough to overcome pure network effect of twitter and reddit

It has been growing fast since the beginning of this year. I moved most of my "aimlessly scrolling through stuff" from Reddit to lemmy.ml .
This is not technically Usenet, but you can access various mailing lists via NNTP at nntp://news.gmane.io. There used to be a browser interface, but apparently that attracted abuse and legal threats.
Usenet (IRC channels too) had a sense of _place_ that I think is less common in mainstream social media, but still exists to an extent in forums, just with a worse interface overall. I remember some things fondly (partly because I was a teenager) but I'd struggle to say it was superior and certainly no healthier than today. I don't remember it being tech-focused or professional, unless you only hung out in comp.* and not alt.*. Like, who remembers Terry Tickle etc?
> Usenet (IRC channels too) had a sense of _place_

Not sure what you mean by this, but they sure were not fully clad with ads and tricks to get you to pay for some virtual gifts or pro-accounts.

There was plenty of spam, to be fair. What I mean is, I don't feel like I inhabit or share a space on Twitter or Facebook (or here) with actual humans I feel I know. I did feel that in various Usenet groups and IRC channels. There's a kinetic, physical quality, an explicit coming-together, like having your favourite, regular table at a pub, compared to standing on a busy street screaming at anonymous strangers. But tbh I don't really seek _out_ those niches now, and presumably they exist.
I think signature lines on the posts helped with that.
I enjoy Twitter but I agree with your assessment. Disagree a little about Facebook though. No argument about FB the company being soulless, evil, etc. But FB groups can be a great experience. Especially the smaller ones focused on a niche subject. Those are some nice communities, but it can take a while to find the right ones.

You're correct about the niches existing. There are little corners of the internet that exist as the neighborhood pub. Not just small FB groups and Discord channels. But I also know blogs still going strong with their 200-1000 regular commentators. The only problem is the audience for those blogs is aging. Not exactly a problem for me since I'm aging too. But does make me a little sad for their longevity because they have a problem attracting new users.

I think the closest I've seen is Twitch chat communities, but obviously that's a very different dynamic overall. I agree with your last point, I am older now, have a company and a family, and I don't really have the same emotional needs as teenage me. I just don't go looking for that level of commitment to internet spaces now. I'm sure in 25 years people will be on here lamenting that Floogleblarg neural pools don't capture the same vibe as Twitch chat circa 2020.
> ... IRC ... had a sense of _place_

IRC is alive and kicking.

IRC is a long way down from its peak both in share of attention and relevance, but yes, probably still more alive than Usenet, although that still also has many pockets of activity.
(comment deleted)
I think a lot of people feel the same way however you need a critical mass of users. I'm just presuming I'm younger than you however I miss the old days of discussion forums, you'd have some for web comics, anime, TV shows all with their set of screen names that you learned and inside jokes that lived on. Along with this is my love of IRC (which I'm still idling in)

Now with the internet feeling like it's just Reddit, Facebook, Google, Discord, LinkedIn, and Pintrest a lot of the fun inside jokes have gone to die, and the groups are so large that no-one even looks at a username.

> Now with the internet feeling like it's just Reddit, Facebook, Google, Discord, LinkedIn, and Pintrest a lot of the fun inside jokes have gone to die, and the groups are so large that no-one even looks at a username.

I've found that niche subreddits are the exception to this rule.

I'm disappointed that NNTP servers and clients didn't get wider use outside of Usenet.

Most public forums back in the day would have been vastly improved if they had been done as an NNTP server with each sub-forum as a newsgroup rather than doing them with something like phpBBB on an HTTP server.

Heck, most forums today would have better threading and post organization with NNTP than they do with the popular web forum systems.

Same goes for non-chat communication within companies. Newsgroups on an internal NNTP server would be better in most ways than mailing lists for topics in which people actually need to discuss things as a group.

Back in the late 90s I had some forum software which would sync with NNTP, either posting from the forum into NNTP and vice versa.

I ran it, and linked it to a new group. Nobody ever posted in usenet, and I suspect nobody read in there.

> Heck, most forums today would have better threading and post organization with NNTP than they do with the popular web forum systems.

I beg to differ.

NNTP's lack of moderation is a bug, not a feature. Between the spam and abuse, NNTP would be an utter cesspool in today's world.

> NNTP would be an utter cesspool

I've seen Usenet, and I've seen Reddit. I'll take Usenet.

You can only take Usenet because Reddit exists. If it didn’t Usenet would be more of a cesspool than it already is.
Whatever platform gets popular is bound to become a cesspit.

If Usenet was as popular as Reddit, you would hate Usenet just as much.

NNTP can be moderated.
Gibson Research (GRC) still runs an active news server, I believe.

nntp://news.grc.com

I also worked for a place in the early 2000s which used an NNTP server internally (large corp) for company communication and discussion.

using NNTP internally was something I always thought would be a great idea: all public discussion (i.e. public to all inside the company, as opposed to siloed conversations in emails or Slack/Teams) and a repository for knowledge transfer (whereas wikis and such are always out of date and usually do not record the arguments that led to a decision)... unfortunately I never saw it used that way at any place I worked at (lucky you).
I’ll take the liberty to re-post what I wrote in a similar thread:

It can be quite difficult to find online oases […]. HN is quite unique. Have you considered starting your own Slack, invite interesting people and build a new oasis? (Or Matrix channel.) It would take some work to get people to join, but it’s not impossible.

https://news.ycombinator.com/item?id=31582270

> Google ended up acquiring and eating Usenet, becoming Google Groups.

That is false and nonsensical. Usenet is a federated network of NNTP servers; Google just joined that with their own implementation having an awful web front end, which they proceeded to revise in even worse directions. That happened right in the middle of a decline that was happening, driven by ISPs shutting down their NNTP servers. So it might have looked like Usenet is somehow transitioning to Google. Google did also acquire a Usenet archive, and then make it impossible to use.

Anhyway, Usenet is alive and (sort of) well. There are new posts daily in newsgroups like comp.unix.programmer, comp.lang.c. Even comp.lang.lisp sees some action.

See you there!

Hey look, comp.lang.awk has a new post, from the somewhat kooky, but topical, KPop 2GM

I'm currently using the news.eternal-september.org NNTP server.

Note: there is spam, but not nearly as much as you see through the Google Groups interface, and that's the interface that offers no filtering features.

You need a newsreader with killfile processing. I use the terminal-based slrn (S-Lang Read News). It has a score feature for assigning scores to articles based on matches on arbitrary fields. If you give something a -9999 score, it disappears. The fields have a lot of information. You can kill based on what server someone is coming from, or what client they are supposedly using, if you want.

The main difference between Usenet and Reddit/SO/etc was posting speed. The Usenet groups I posted in were slow by today's standards. No one expected an immediate response, and the groups didn't hide things after a few hours. Paging back through 5 or 6 pages of threads in `tin` was common. The equivalent today is probably a subject-specific mailing list.
stackexchange.com isn't a full replacement but definitely fulfills some of the use cases of Usenet.
Yep, as long as it's vaguely a "question", the smaller communities have very different tolerances to opinion-based-ness. It's subject-focused, and the quality is generally pretty high (StackOverflow is a different beast though, due to sheer scale)
