A bit paradoxal but it looks that all central platform (twitter, reddit, facebook…) are helping the spread of Fediverse. Recently we saw the impact with Twitter on Mastodon, myself I’ve discovered Lemmy even if I wasn’t a reddit user. And before that Facebook first spread friendica and diaspora. It looks next step will be around Youtube where Google try to lock more and more its user.
I’m also of the understanding that the way other current federated protocols handle video is far from efficient, that google using activitypub for YouTube would be a nightmare.
