I think there's probably an upper limit for how big any community can become before it becomes fractured. This size is probably variable, and dependent on the medium and structure of the community to an extent, but I'd posit it exists for any community. See: reddit, Stack Overflow, Facebook, any church, any religion, any politcal party, any country. Often secession is what happens: new subreddits, new churches, new countries. But as they grow, the same problems return. One thing I've often thought about is some kind of community-space with a fixed upper-bound on the size of communities, essentially forcing a community to split to add new members, like an old cell.
