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.
The main issue is monetization. With social media, nobody cares about getting paid but Youtube or Twitch channels are the main revenue from lots of people nowadays. Not only the creators but also editors or writers.
I could see a patreon/floatplane style system where you only get the livestreams if you pay, or video releases are delayed for a week if you don’t pay. Video sponsorships also make more money than Youtube ads I think.
