ActivityPub is now a W3C recommended standard

The Free Software Foundation blog has a guestpost from GNU MediaGoblin founder Christopher Lemmer Webber announcing that ActivityPub has been made anofficial W3C recommended standard. "ActivityPub is a protocol for building decentralized social networking applications. It provides both a server-to-server protocol (i.e. federation) and a client-to-server protocol (for desktop and mobile applications to connect to your server). You can use the server-to-server protocol or the client-to-server protocol on their own, but one nice feature is that the designs for both are very similar. Chances are, if you've implemented support for one, you can get support for the other with very little extra effort! We've worked hard to make ActivityPub easy to understand."
