Imo Stack Overflow has absolutely been destroyed by the moderators. I was (and still am) in the top ~%0.80 of users[1] but no longer contribute to the site (I stopped ~6 years ago) because of the moderators. It has been an absolute shitshow of closing questions that shouldn't be closed, anally-retentive nitpicks which intimidate new users, the essential nuking of the community wiki (even prior to the official deprecation), bad answers being upvoted, good answers being deleted, and so on.
The whole "community moderator" thing ended up being a popularity contest where typical nitwitted social climbers ended up injecting themselves in every single minor conflict on the site just to score visibility points come community voting time.
On top of this, SO is also dying as it has no real viable way of cleaning up or deprecating old answers, and if new ones are asked, they are closed in favor of the old (outdated) ones. Slowly, reddit and language forums/mailing lists are becoming more and more valuable as Stack Overflow becomes more and more of a trash heap. It sucks because I really really loved Stack Overflow, but it just broke my heart one too many times.
