#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.
@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.
