This is more of a combination of a web server and a web framework, which is what I find fascinating about it. Twisted has had a web server forever, but despite a significant amount of experience in Twisted Land, I'd never write a full app using it! Add to that the (apparently) standalone low-level modules and we've got some seriously awesome tech that FriendFeed/Facebook have supplied for free.

Thanks a lot, fellas. Asynchronous networking programming in Python is somewhat of a bear so it's really nice to see a tool get released that improves it!
