"I think it would also help if there was a sentence in that section explaining that MyApplication.FillInView is seperate so that you can reuse it with multiple views by .extend(Views.Tweet, MyApplication.FillInView); (I think that's called a mixin?) and maybe another sentence explaining how the 'this' context allows it to work.
