The thing about general threads is it's only as good as the willingness of the participants to be engaged with the topic at hand rather than spamming tired memes and gossiping about the other users. It's more of a problem with low-effort chatroom-tier posting than being about a general topic necessarily. I'd say it would become a 'general' if there is no new content and it's the same flood of people doing the same things over and over.
