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?
peruse all and block communities you have zero interest in while subscribing to things you like. Eventually to check your subscriptions first and when caught up you check all to see if anything new catches your eye.
