Honestly a self-hostable HN clone, so no rings/communities/subreddits or anything, I think could be kind of cool. 1 community per server, so they stay naturally pretty small. If you find a post out in the wild, the domain name tells you exactly what the general topic is. You could use activity pub to handle a “personal front page” that includes stuff from other instances per user. Maybe a bit naieve but that’s basically what I’d want at this point. Maybe I just want ye olde hyper-focused forums?
