Thanks for the idea, however I'm not sure of how I feel about that. If any of those topics particularly interests you, then sure, we can open some of them. But I wouldn't rush opening a community for every topic on Earth, just for them to remain empty and forgotten. After all, there's plenty of general purpose instances we are federated with, out there.
And more importantly, the reason why I said "you most mod it yourself or know someone that would" is because I don't want to spend my days as a janny (and of course we can't have modless communities either), so that's still a pretty important point to cover imo.
Yeah I agree on that. I've already seen two text posts in !pcm@lemmy.basedcount.com that didn't really have anything to do with PCM but of course the people there didn't have another place to post them in.
How do you think such a #general community could look like? Something like !main@sh.itjust.works ? A strictly helpful !support@beehaw.org? Or pure chaos like !lemmyshitpost@lemmy.world ?
