I suppose the confusion is because duplicate Lemmy communities across instances can haver the same name. Perhaps a solution to this would be to more prominently show the instance name alongside the community name.
I imagine we will get situations in the future where multiple same name communities gain traction, but may have different vibes. If it was easier to tell apart c/foobar on InstanceA from c/foobar on InstanceB on each part of the Lemmy interface it would be less confusing.
