Not dead but definitely on life support. I really do miss old forums. Reddit / Discord / Fediverse don’t come close to the old community feel. Facebook groups aren’t so bad sometimes for that but then the content is organised terribly. Say what you will about forum search engines but I could always rely on being able to enter a keyword or two and get what I was looking for.
A lot of forums I frequented were actually pretty well organised with subforums. It just isn’t the same these days.
Also web forums were the absolute best for petty drama. I do miss that in a weird way. Always that one angry gatekeeper flaming everyone.
