I love that nostr identity is not tied to an instance (unlike activitypub/mastondon/fediverse)! However ignoring some (IMO) fundamental problems (because they are not problems until you hit scale) like hosting, somewhat moderation and letting that be solved "layer above" is a mistake (IMO) it will probably create non standardized APIs for paying for hosting or sth.

As for community it is heavily based on bitcoin/lightning enthusiasts and a lot of content revolving just around that - probably won't attract people outside the circle/general public (which may not be the goal or preferable outcome!)

I think Bluesky/atproto has a reasonable compromise in this department. At any single point in time your identity is bound to a specific instance, but that binding is mutable.

You might be surprised on how relatively popular it is among some Japanese users. They have their own clients and relays and most of them are not even into Bitcoin.
