@evanEvan Prodromou Having heard of ActivityPub relay servers, it seems to me that relay server owners and regular instance owners can pick and choose what to broadcast (including filtering algorithmically), which relay servers to broadcast to, and which relay servers to receive broadcasts from.

So in other words, don't have regular instances broadcast to regular instances, but rather use relays for that purpose, which then allows distributed choosing.

@virtuous_slothBruce Elrick Meh. Relays are a Mastodon-only feature -- they're not part of the ActivityPub standard. I think the topology of an opt-in pool of servers that all share their public activities is fine, though.
