They should have leaned into becoming a developer community (the developer community) instead of focusing on Q&A. StackOverflow jobs were a great resource. Add an ad-hoc discussion forum and chat and it would have be great, like the modern IRC.
Disagree, the Q&A format is good, but the moderation isn't.
Instead of current practice, they should make a separate "hall of fame" Q&As that meet their standard, and no more "too broad" "duplicated" closed questions.
Only close / deletes questions that aren't relevant, like jokes and out of topics (careers) questions.
