I feel like this might be mistakenly conflating the strength of the diversity of the fediverse with the convenience of using a single platform or UI for "everything".
I don't think the former necessitates the latter. Moreover, I suspect that the former is suppressed by the latter. Feeding blogs, groups and forums, microblogs, video+audio platforms etc all into a single twitter-like UI/platform ... seems like maybe a bad idea.
