And there's more! PeerTube uses <a target="_blank" rel="noopener noreferrer" href="https://activitypub.rocks">ActivityPub</a>, a federating protocol that <strong>allows you to interact with other software</strong>, provided they also use this protocol. For example, PeerTube and Mastodon -a Twitter alternative- are connected: <strong>you can follow a PeerTube user from Mastodon</strong> (the latest videos from the PeerTube account you follow will appear in your feed), <strong>and even comment on a PeerTube-hosted video directly from your Mastodon's account.</strong>
