Hmm.<p>IRC, Usenet, and PHPbb to an extent we're all open protocols. And of course Email.<p>Finger, SSH, BBS? XMPP.<p>I don't think that a revolution is what Fediverse should be aiming for. Let's start with 'useful', and this seems quite useful. If this lasts longer than IRQ or AOL Instant messenger, it's a success. If it lasts longer than that, a huge success.<p>The big thing this year is that people have begun to realize the issues with these walled gardens. So we as a culture have learned and improved as a people, and can appreciate the importance of an open protocol like Mastodon.
