we need to be even smaller

The point is that having everything be on one instance results in the centralized abuse of power we saw with reddit

Per example: .world has some famously bad power mods (a certain soaring mollusk comes to mind) same as reddit, growing communities outside of that centralized area gives us a place to run when they finally snap completely, as is inevitable with power mods

This is very easy to do thanks to how Lemmy works
