Every interesting question just shows a bunch of deleted comments, so I stopped looking at it a while ago.
There is another sub which tracks answered questions. Its a side effect when focussing on quality.
Not really, if you want to ask a question. 9/10 times it gets locked for breaking some obscure rule. If anyone answers, that answer is just deleted immediately as well.
This type of subreddit specifically is almost entirely useless since the advent of AI.
It depends. I have compard some answers with my discussions with different llms and i still find the answers in the sub qualitatively better.
