Less community repetition. I feel like it spreads out potential members and makes each community smaller with repetitive content. I wish communities could be more linked so they share content and members.
I've had a thought, what if clients allowed users to mix and match communities so that they show as one? You could bundle all the gaming communities into one for instance. You'd still see where each publication originates from but they would appear in the same feed
One idea: Community owners can link their community with another, like friend requests between communities. From that point they act like one community with multiple owners. Everything is duplicated, and that includes removing content and banning users. Client side apps can show them as one community.
