Without constraining yourself to Mastodon/Misskey/Pleroma/Frendica/GoToSocial/other current social implementations and/or the current features of them (meaning quote and threading is already accounted for in the question) what would *you* want that you haven't seen?

For that to work, we would need a new kind of TCP/IP I guess, not even IPV6 stuff. But I am not the expert for that. However, "distributed anything" with federated authentication is what I think we need - but seriously no #blockchain voodoo.
