'm very proud to say that the W3C working group I've been involved with for the last couple of years has published a Candidate Recommendation for Activity Streams 2.0.

Activity Streams is a JSON format for encoding information about activities on a social network. Who posted a status update? When? Who liked it? Who commented on it, and what did they say?

The format allows social networking software to interoperate -- exchanging information about people and stuff on the networks in a standard way. That helps with doing things like backing up your social network information, or sending live updates between networks.

Programmers should start implementing Activity Streams in their software ASAP. Non-programmers should start asking for Activity Streams support in the software and services they use.

Thanks a ton to friends and colleagues on the W3C Social Working Group for getting us to this point.
