I was hoping they'd leapfrog GitHub and allow you to stage actual commits and use something like CodeMirror to edit.
Isn't that exactly what they did?
Both GitHub and BitBucket are really close to letting me do significant editting of code from my browser which is still very useful for me. There are tons of times I'd love to be able to fire up GitHub and hack on some files without having to actually commit to persist changes. But then again, maybe I'm projecting feature creep on what is ultimately a VCS.
