Even more than cohost (which despite recent events I still kinda adore as a format in general tbh) I crave the concept of a Digital Small Town where a community of like maybe 200-1000 monthly users do stuff like integrated game nights and stuff. I remember the old PlayOnline browser for FFXI from SquareEnix that was like this walled garden internet with chatrooms and forums and stuff anf I want like. An App that was a lot like that but designed specifically around small communities of roughly that size.
I wanna have to get a passport to another community operating in a similar capacity, by some sorta proximity based on proportion of shared personal connections between however many links in a community, to show up at a cool event scheculed as if I'm some high schooler in a small town in a small town in Indiana to a punk show in Indianapolis.
That's the ideal way the internet should work on a human scale, IMO.
