@marek I personally want/use Friendica as the Facebook UX replacement on the fediverse. The closest thing besides that is Diaspora but DIaspora only federates with the Diaspora protocol not with ActivityPub. On the video questions, that is actually a very interesting question. Media upload in general right now is clunky through the UI. It is one thing I want to fix with the mobile/desktop client I'm working on. Adding short-form video could be interesting but would maybe explode the serving requirements if adopted too liberally by users. That doesn't mean one shouldn't do it. It's just need to be cognizant of it.
