#lemmy/#kbin has a problem that #mastodon hasn't even attempted to solve; groups and what happens when they get popular.

#Communities, #groups, #magazines, whatever they are called are implemented as #Actors in #ActivityPub. They are basically just *very* popular users who boost a *lot*.

You can't just distribute them across instances the way normal actors do. Whichever server hosts @[email protected] or @[email protected] is going to get HOSED on the regular.

In those cases, the action will need to propagate back to the home server (that's where the "hosts of popular communities will get more traffic" comes from), but keep in mind - people usually read at least one or two orders of magnitude more than they write.

@sunaurus there's a lot of upvoting happening on popular subreddits

Absolutely, but a user will only upvote a post once, while they will read it on every reload of their page. (By "read" I mean "fetch it from their local mirror")

Hmm, you could probably extend the protocol to do eventual consistency across instances if that ever becomes a problem, remote instances could keep their own counts and only send aggregated updates.
