There was definitely a bit of Pournelle's Iron Law of Bureaucracy [0] at work. I worked there during a lot of the drama you allude to, and... It sucked, for everyone. But also...

For most of SO's history, the vast majority of visitors (and this questions, answers) came in via Google. Not "search engines"; Google. This was pretty much baked in right at the start, and it effectively served as the site's primary user interface for years. And it worked. It worked pretty well! Until it didn't.

At some point, Google started surfacing fewer "tried and true" Q&A examples and more unanswered, poorly-answered or moderated examples. This broke the fundamental assumption that sat behind SO's moderation - that curating a smaller set of posts was preferable to encouraging more, and newer. Suddenly, Google wasn't a very good UI for SO anymore.

...and SO didn't really have a fallback. Heck, for a while during this period they actually stopped showing questions on their homepage unless you were already logged in; the core assumption remained that there was a never-ending spring of new people feeding the thing. LLMs weren't the start of the problem, they were the end - the final wake-up call.

I don't know that a site like SO can exist without the old Google, the old Internet; it is a product of all that, in the same way that mass-market TV shows were a product of 20th-century broadcast technology, or trade paperbacks of a particular intersection of printing tech and reading habits.

I know the feeling of being happy not being the only one with that same problem (and that somebody bothered to actually ask on SO) and the crushing feeling that the question was closed as off topic (so no reason for me to ask) or marked as duplicate (referencing that is clearly not a duplicate and just showing that the mod took no effort to understand the question)

The moderation definitely got kind of nasty in the last 5 years or so. To the point where you would feel unwelcome for asking a question you had already researched, and felt was perfectly sound to ask. However, that didn't stop millions of people from asking questions every day, it just felt kinda shitty to those of us who spent more time answering, when we actually needed to ask one on a topic we were lacking in. (Speaking as someone who never moderated).

My feeling was always that the super mods were people who had too much time on their hands... and the site would've been better without them (speaking in the past tense, now). But I don't think that's what killed it. LLMs scraping all its content and recycling it into bite-sized Gemini or GPT answers - that's what killed it.

I asked a question for the first time mid last year. It was a question about "default" sizes in HTML layout calculations, with lots of research and links to relevant parts of the spec.

It was immediately closed as off topic, and there were a bunch of extremely vitriolic comments offended that I'd ask such a question on SO. It was briefly reopened weeks (?) later and then I guess closed again and now is deleted, so you can't even view the question any more.

I'd long heard of abusive moderation but... experiencing it first hand is something else. Anecdote of one, but I know I'm never going to ask there again.

In case anyone's wondering, I ended up asking on the WhatWG or W3C or something github project (via an issue?). The TLDR was rather eye opening, that basically the spec only codifies points of contention for browsers and old behaviors are generally undocumented. With some pointers I figured out the default size behavior through code diving, and it was complex (as in, hard to use) and very unintuitive.

Friend in my group was in the public beta back in '08. We all ended up signing up by the end of '09. I used it off-and-on over the years (have some questions and replies with hundreds of upvotes). Though SO had a rap for having what might seem like harsh replies or moderation, it was often imho just blunt/curt, to the point, and often objectively defensible. I also agree with your timeframe that, in the later 2010s, the site became infected with drama, and moderation suddenly started reaching its tendrils into non-technical areas, when it should not have. And on an ostensibly technical site, no less!

I found myself contributing less and less (same with Wikipedia), because I merely wanted to continue honing my craft through learning and contributing technical data with others who shared this same passion... I did not want to have politics shoved in my face, or have every post of mine have to be filtered through an increasingly extreme ideology which had nothing to do with the technical nature of the site. When I had my SO suspended with no warning or recourse for writing "master" in a reply, I knew it was time to leave for good. Most of the admins on the site transformed from technical (yet sometimes brash!) geeks, into political flag-waving and ideology-pushing avatars (including pushing their sexual agendas front and center), and not of the FSF/FLOSS kind, either.

These types of dramas have infected nearly everything online, especially since 2020. Even Linus has lost his mind with pushing politics into what should be purely technical areas https://news.ycombinator.com/item?id=41936049

LLMs were a final blow for many reasons, though I think that a huge part of it is that LLMs won't chide you and suspend/ban you for wanting to stick to strictly technical matters. I don't have to pledge allegiance to a particular ideology and pass a purity test before asking technical questions to an LLM.

Quite frankly you are wrong. Jeff and Joel spoke about their goals for very harsh moderation in their podcast while they were still building SO. The moderation from the very beginning was a direct result of the culture they created and it was completely intentional.
