What we’re really lacking on the ui end is a way to see groups of identical communities that are on different federated platforms. Hence the idea of a dom-lemmy. The way it would work is lets say you search for a cat community called “cats”, there’s at least dozens of them out there already. Instead it would return the cats dom-lemmy, with the option to either drill down to a specific instance, or to merge all sub-lemmys called cats into a single view
In the days before Reddit ‘won’ you used to be able to find tons of niche sites/boards cultivating smaller audiences. Beer advocate/rate beer, headfi and whatever the latest splinter was there in the audiophile community both come to mind. There’s generally more division by which each might find more ‘aligned’ or maybe their friends are on one first.
I don’t know if it’s possible to predict, social dynamics are weird and this is going to be new for a giant segment of the audience.
