Have you met Guppe Groups
https://a.gup.pe/

Groups are different from #hashtags in an important way: you will only see posts with hashtags your instance knows about — it's essentially a search feature. With groups it's different: if a remote account from the other side of the #fediverse posts to a group you follow, you will get it!
Anyone can create a group just by following it.
