Oh these are fantastic! Cappuccino has some really interesting interfaces and muze.nyc is a beautiful mess.

Have you used any of the apps that you mentioned? I'd be curious to know if the communities in these spaces actually feel special or if it's just the same old same old with a new interface.

I've also noticed that though they all look wildly different, they seem to share a particular vibe. Maybe this aesthetic is waiting for a name to be coined!
