@rabble and @kellan gave a really important talk at OSCON 2008 called "Beyond REST? Building Data Services with XMPP PubSub".
They talked about how the feed-polling architecture was costing an arm and a leg for publishers with only tiny benefit to users.
I was in the audience and it was a really important inspiration for later work.
