Please support the PubSubHubbub Community group

Folks,

tl;dr version: There is a new community group proposal for a 
PubSubHubbub community group. Please support it.

    http://www.w3.org/community/groups/proposed/#pubsub

Long version: PubSubHubbub <http://code.google.com/p/pubsubhubbub/> 
("PuSH") is one of the key technologies for an open, real-time Web.

It uses the Webhooks <http://www.webhooks.org/> pattern to let 
subscribers register interest in an Atom feed, and to let publishers 
distribute updates at time of publication, rather than at a later poll time.

(If you think that's not a big deal, I highly recommend Evan 
Henshaw-Plath and Kellan Elliott-McCrea's great talk at OSCON 2008 
<http://radar.oreilly.com/2008/07/oscon-day-1-beyond-rest-buildi.html>. 
They discuss the problems with polling many feeds at scale, and propose 
a pub-sub solution, albeit XMPP-based.)

The specification for PubSubHubbub was originally developed by Google 
engineers Brad Fitzpatrick and Brett Slatkin (cc'd). They have a good 
video <http://www.youtube.com/watch?v=B5kHx0rGkec> that goes over what 
the protocol does and why they developed it. There's also a demo from 
the 2009 Real-time Crunchup <http://www.youtube.com/watch?v=ewQBgbysSOQ> 
with similar info.

In the years since its first release, the PubSubHubbub has been 
remarkably widely-implemented -- on blogs and in feed-reader 
applications. New usage has turned up some new requirements. Among other 
things, defining how the protocol works for non-Atom data types (like 
Activity Streams JSON or even binary types), and defining how to limit 
distribution to particular individuals.

Brad and Brett have, I understand, given their support to a new 
community group. (Correct me if I'm wrong, guys.) The original IP is 
licensed under the OWFa agreement, which I believe is compatible with 
W3C community groups.

I am interested because PubSubHubbub is the key component to OStatus 
<http://ostatus.org/>. StatusNet and Identi.ca host almost a million 
PubSubHubbub-enabled feeds. I hope other people and organizations 
interested in the FSW can support this new group, too.
