I guess one could be generated by getting instances and then their instance lists and having it auto-generate, I was kind of thinking of like the music map site for example: www.music-map.com/ludwig+van+beethoven

mostly what I’m wondering with this question is which instance(s) would be best to sign up for if you want to post something that will federate with a ton of other instances

or can you think of “factions” among those in the fediverse? for example I think beehaw defederated with lemmyworld and shhhhitjustworks, and I think most defederated with threadsdotnet… so the idea is that with a handful of accounts you could reach a lot of the fediverse
