FriendFeed has an in-house framework inspired by web.py and Appengine's webapp. It was written by Bret Taylor, who was the PM of appengine when it started, but is now working for FriendFeed. He mentioned that he might open source it, but hasn't done so yet. I encourage people to put some pressure on him to do this =)! http://bret.appspot.com/entry/experimenting-google-app-engine http://bret.appspot.com/entry/experimenting-google-app-engin... EDIT: I'm not sure who wrote the framework, so I was wrong to say that Bret wrote it. In any case, it was written by FriendFeed developers.
