Nostr does some interesting things! What I mentioned here is actually just the identity part of what I think could be a significantly improved version of the fediverse. I have ideas on how to support subreddit style communities and decentralized moderation and things like that that make the whole idea a bit different from nostr.
I suspect retrofitting a whole new identity system to Fediverse will never happen because server admins, or instance admins, will come up with all kinds of reasons why they don’t like the idea of not knowing who their users are. Some of them would probably allow it, but I bet a whole bunch of them wouldn’t, and we’d get into this fragmentation where some servers won’t allow posts from those types of identity, etc. It seems to me much easier to take Nostr and just give it the functionality you get inside the Fediverse.
