Oooh opinions(ish)! I'll throw mine in: in social interactions (IRL & online) people are interested in 'finding groups of like-minded individuals' across multiple interests. We switch between those groups often. In that model there is no one-size fits all structure, we have different circles of people in differrent places. This is something that the Fediverse reflects well IMO. Where I see value in being 'one network' is the cross-pollination between those circles.
