I believe more and more people will escape to lemmy sooner or later, and I already see 3 different communities for the same thing (selfhosted) here on lemmy. Time will tell which one will be the most active, but lets assume all of them will be equally active and the desire emerges to combine the two communities about the same thing, is that something possible or intended to be possible with federated services?
Yep, that’s exactly what I mean. Coverung the same ground, but they are different communities with different moderation, so it can’t be merged, but it make sense to group them together and view it as a “playlist”. Just like Whitney Houston and ABBA don’t collaborate to make albums, but it make sense for their songs to exist together in a playlist called “Songs from the 80s”.
