Makes sense, I also think the original post would make more sense if it were talking about the distribution of large communities. For instance, if there wasn’t so many of the largest communities on the same 2-4 servers, then I think browsing would be a lot smoother. In addition, I think users who say care a lot more about a certain community may choose to use that other less populated server to be their home, as it is the home to that community.

(Just a thought, I have done ZERO work with federation or ActivityPub)
