Hey up,

I've heard of it but haven't been following it. I've noticed also some pushes for e.g.

http://opensocialweb.org/

Note the links on the right too. I like this more: it would mean that our own social data could be stored where we liked, and collated in any way code allows, as is the case currently with RSS, but with personal control over privacy settings. Given how massive facebook is, I really hope the future has something as fundamental as HTML for social interaction. I mean, look what's happening in Egypt too (though also, I see, Google seem to have been helping people get round the net block...)

Interesting times!
