No, what I want is r/RPG - a single, central hub for RPG-related topics. Yes, there are also subs for RPGDesign, DnD, DM advice, etc., but RPG serves as both a central community and as a hub for all those more specific groups. There is no way to have a “hub community” on the Fediverse, or to efficiently find all groups which share interests. Groups which had a “largest community” on Reddit will now find themselves shattered and separated. Sure, you can say Federation will save them, but it really won’t. All federation means is that now instead of one community, there’s one per server, and you have to know to subscribe to each and every one of them.

Sure, there’s Mastodon’s Lists feature, which works like a Multireddit, but that’s honestly a lot of effort, and doesn’t cover Lemmy or kbin posts like this one. We need a way to automerge common communities, at least in the user’s view.
