Original clunky title: How do ActivityPub instances’ people initially find remote instances’ people/communities/channels/etc. to vary their feeds?
Given that an instance won’t see remote instance’s people and stuff to follow/subscribe to until someone there has found them and followed/subscribed…That’s generally how ActivityPub works, isn’t it?
New PieFed instances download a list of communities from an instance of your choice OR https://lemmyverse.net/ and automatically subscribe the admin to communities that match certain criteria (recently active, reasonable number of subscribers, etc).
