I was talking about this with friends. I think that as the userbase grows, we'll reach the point of specific communities being like the "main" sub for that topic. Like, right now I'm subbed to 5 or 6 different "games" or "gaming" communities. Eventually, I think whichever instance ends up with the largest one will essentially become that default you're looking for.
That said, I don't think forcing it by collapsing alternate communities on different instances into one is the right way to proceed, because that may not be inevitable. I mean, maybe the [email protected] culture is different enough from the [email protected] one? We had r/games, gaming, truegamers, gaming4gamers, girlgamers etc etc on reddit, you know?
tldr: I think that, while communities for specific topics slowly shifting towards one mega-community seems likely, there's a space for different smaller ones with different moderation and culture here too.
oh, that's really neat. thanks for the link!
yeah, agreed, I'd love something like that for the fediverse. Honestly, it feels like accessing various communities from different instances would actually feel more natural with it all being fed through the terminal for some reason.
