Seeing a big “politics” community in both lemmy.ml and lemmy.world just confuses me as to which I should be subscribing to and I don’t really want to subscribe to both.
Guess this is just a downside of federated instances? There’ll never just be one “/r/politics” on Lemmy?
The major concern is whether to cross-post so that members of only one community can see posts from the other, or to avoid cross posts so that people subscribed to both don’t see duplicates
As with almost every other question about the fediverse, we already discussed this to death decades ago and came up with the answers for email. Do what you’d do for two mailing lists on the same topic.
