I've noticed in the explosion that we are getting duplicate communities in multiple instances. This is ultimately gonna hinder community growth as eventually communities like 'cats' will exist in hundreds of places all with their own micro groups, and some users will end up subscribing to duplicates in their list.
A: could we figure out a system to let our communities know about the duplicates as a sticky so that users can better find each other?
B: I think this is the best solution, could a 'super community' method be developed under which communities can join or be parented to under that umbrella and allow us to subscribe to the super community under which the smaller ones nest as subs? This would allow the communities to stay somewhat fractured across multiple instances which can in turn protect a community from going dark if a server dies, while still keeping the broader audience together withing a syndicated feed?
Yes, that works of course. What I like to do is look at a specific topic when I want to. Let's say, I'm in the mood to only check out literature/book related stuff. I'd like to open my "Multimagazine" (I saw someone call it a rack, which I think is a nice analogy) where I only see posts that belong to this topic.
The only thing that's a bit painful now is finding narrow topics. Reddit had grown so big, you can almost guarantee to look for niche topics. On here, you're better asking /m/random.
In a year or so, if fediverse can grow nicely, maybe we'll be asking top level instance to recommend the best community, and rebuild your niche collection.
