It is probably due to a number of people stopping using their alts after some instance hopping.
Also a few people who came to see how it was, and weren’t attracted enough to become regular visitors.
Curious to see at which number we’ll stabilize.
Next peak will probably happen after either major features release (e.g. exhaustive mod tools allowing reluctant communities to move from Reddit) or the next Reddit fuck up (e.g. removing old.reddit)

Propagation and agglomeration is a problem for clients not servers. Server only need to propagate a “we have new stuff” message and it’s up to the clients to pull it and cache it. In any case, users should be able to click /c/books and see the content of all /book/ on all instances in a single location. Unless most users can do this with one click, there will not exist a fediverse wide community.
