Passive aggressive commenting and deleting questions because it looked remotely similar to another one was enough for me.
I was there for learning and sharing, not for the proverbial fighting cage.
I can spend 5 minutes more and use a search engine, and then take my own notes and keep them to myself. Thanks.
I think since AI finally provided a non-adversarial alternative to Stackoverflow it lost the critical mass to be a one stop shop for all tools/languages/projects. So people just reverted to communication forums specific to those tools/languages/projects.
There are plenty of project mailing lists, GitHub issues, language forums, blog posts etc. that are still active. E.g. just the Rust users forum gets more than 2-3 posts per day.
I'm not saying LLM won't be able to train further, but tough and sound reviews are paramount to improving the corpus of quality content. And with the replacement of SO by LLMs, one can wonder if one quality system went down the drain. Anyway there's still code reviews on GitHub and in private repos, but we're still far from getting the human judgement out of the loop.
Absolutely.
"SO's upvote system and reputation system is what really refined quality."
Absolutely not!
SO's problem was exactly that they gave average users moderating power. That lead to half of the questions being closed because they were over the head of the average user/moderator regardless of being interesting and useful questions or not.
