If you want people on Mastodon etc to follow your PeerTube, it's important that you encourage them to follow your PeerTube account instead of your PeerTube channel.
When people from Mastodon etc follow PeerTube accounts, videos will start to federate to their server and show up in their timelines on Mastodon etc.
However, if they follow a PeerTube channel instead of a PeerTube account, the videos may not federate to their Mastodon etc server at all.
