All I'm saying is that if /c/butterflies exists on multiple instances they should be able to "aggregate" themselves as if they were one instance. We don't have enough users to isolate small communities; they have no shot here.

If large federated communities want to exclude others... those others can just form their own federated group. We're still in a much better position than if we had one large community on a single instance or a speckling of tiny ones across the fediverse that aren't large enough to drive engagement.

In the current model small communities are forced to choose a server. When that server goes down we lose an entire community. Two examples off the top of my head are Firefox and Android. We can't count on legends to save us every time. And why go through that chaos when we have the underlying systems to avoid it?
