Stack Overflow Went From 200,000 Monthly Questions To Nearly Zero (stackexchange.com)

(Monday January 05, 2026 @11:41AM (msmash) from the how-about-that dept.)


Stack Overflow's monthly question volume has collapsed to about 300 -- levels not seen since the site launched in 2009, according to [1]data from the Stack Overflow Data Explorer that tracks the platform's activity over its sixteen-year history.

Questions peaked around 2014 at roughly 200,000 per month, then began a gradual decline that accelerated dramatically after ChatGPT's November 2022 launch. By May 2025, monthly questions had fallen to early-2009 levels, and the latest data through early 2026 shows the collapse has only continued -- the line now sits near the bottom of the chart, barely registering.

The decline predates LLMs. Questions began dropping around 2014 when Stack Overflow improved moderator efficiency and closed questions more aggressively. In mid-2021, Prosus [2]acquired Stack Overflow for $1.8 billion . The founders, Jeff Atwood and Joel Spolsky, exited before the terminal decline became apparent. ChatGPT accelerated what was already underway. The chatbot answers programming questions faster, draws on Stack Overflow's own corpus for training data, and doesn't close questions for being duplicates.

Yes, the Wikipedia similarity is because of the similarity of the contribution models. The core problem is moderation - you need rules tight enough to keep overall quality high enough that people trust it enough to want to visit. But doing that raises the cost for all contributors high enough that a lot of folks don't want to put up with it.

Kind of an idle question, but I wonder if Spolsky saw it coming or got lucky.

This is both reason for success of SO and the cause for being the perpetual punching bag. Since there was a high amount of moderation the answers were way better than sorting through forum posts. But people care about their question being answered and don't care that the added volume of duplicates makes the site less searchable for others. And for people answering getting moderated for "good enough" answers is often a stronger deterrent to contribution than fake internet points and altruism is an incentive.

My concern is that the replacement really isn't sustainable. ChatGPT is not going to get better, the concept is ultimately technically limited to the level of reliability we see today, and without people publishing answers to more current questions, it's going to get stale and lose its usefulness pretty quickly.

I still find it hard to understand why that's so difficult for generative AI boosters to grasp. How will it be more accurate in 2035 if most of the information it bases its output on comes from 2025?

And by "using" Experts Exchange, I mean a link to a post on their site would come up when I would search for something online. The answer was ostensibly paywalled, but all you had to do was view source and the answer was right there, buried in the HTML.

I was involved with Stackoverflow in the early days and it really was a gamechanger. It was so much better than trying to find your answer by slogging through forums, that it really took off. And gamifying the answering of questions really helped it grow fast. But there's always this point where the community gets swamped with rules-obsessed bureaucrats and drives the original contributors away, and that's what happened with me. The mods all became power-trippers obsessed with closing questions and keeping people in line, rather than the original purpose of helping people. And while Stackoverflow was in decline, LLMs are a massive nail in its coffin. Why would ask a question on Stackoverflow, only to be treated like garbage, when you can ask a chatbot the same question and have it confidently tell you a subtly wrong answer, but politely?

I often went down the path of implementation suggested only to find that the problem was solved in a more modern way after a version update. The community just couldn't keep up with the evolution

StackOverflow's Own Fault (Score:5, Insightful)

by Carcass666 ( 539381 )

While I am not "vibe" coder I find myself increasingly using AI to get questions to answers that I used to post on SO, and getting pretty good results. Asking a question on StackOverflow has always been a last resort, because that is the way they want it. There is often as much energy expended on why a question shouldn't be answered as opposed to answering it. The mechanisms to search for an existing answer are not good enough to keep you from DEITY FORBID posting a duplicate. Also, the site is not good at dealing with stale content. The "accepted" answer is often no longer the currently correct answer. The level of snark and condescension is significant, and while I don't mind a bit of sarcasm now and then, I don't want to get in continual debates with someone on whether what I'm trying to do is worth doing.

Contrast the experience with AI tools. They do not yell at me for asking a question that could have been found via web search. I do not have to wait, I get an immediate answer. Yes, these tools are overly sycophantic, and sometimes they are wrong. But 90% of the time I will get a workable response and I can choose to have my code updated based upon the answer. In those cases where I don't get a workable result, I either post an issue on the repo (open source) or contact the vendor (closed), which isn't all that different from what I do with SO

Peer-based discussion are useful, and if sites like Stack Overflow disappear, we've lost something. SO can perhaps remain relevant by being better at facilitating deeper design and architecture discussions and leave the simple "how do I" questions to AI.
