Our special guest on this week's Podnews Weekly Review is the wonderful @evan the co-author of the ActivityPub protocol and ActivityStreams 2.0 #W3C
The ActivityPub protocol is a decentralized social networking protocol based on the ActivityStreams 2.0 data format.
These are both W3C open web standards.
For the last few months, Evan has been writing a book about ActivityPub for O'Reilly.
The first two chapters are now available. You can read it here!
