I need communities to be like #tags. - I can have multiple ones for one publication - crowds behind each of them come together in the comment section But unlike #tags, communities come with moderation, hosting, etc... And I as a creator can outsource those things to the communities I select (which can include my own, if wanted). And it comes with a kind of global state around my publication, without needing a Platform to provide that.

Linear, Notion, Figma, Autodesk, Proton Drive... are all 10x more worth building alternatives for than any big tech social platform. They're productivity tools. You can build transparent, honest, small businesses on things like that.
