Stack Overflow had been a zombie even before they sold to Prosus in 2021. It became over-moderated and calcified.

Amongst even simple stuff, they refused to update basic library questions when said libraries had new releases with additional calls and performance enhancements.

Sometime in 2018 I went so far as to blacklist the domain so it wouldn't inadvertently pollute research.

Yea, I abandoned it before then too - it was clearly over-filled with old answers with no context as to if they're still valid.

Everyone has had the experience where the top response was right for 3 months, but is now impossible to fix, so you have to just somehow know that you need the 19th answer with only 6 upvotes (versus 387). That was a problem early on, and afaict has exclusively worsened over its whole lifetime. They seem to be proud of it as if it was a major feature, and have afaict never built anything at all to try to address it.

(Yes, editing answers is "a solution", but you can't do that as a newcomer who knows better. You've got to commit to the ecosystem for months... when it had just failed you. Of course most visitors don't do that!)
