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?
No you don’t. Federation means you can subscribe and post in a community on one instance with the account from another instance.
