Thanks for the tut.
But, I'm missing a point here. Yes, the chained ->then calls execute in sequence to the returned promise, but how is this asynchronous? You're still blocking on the http function call. If I can do the same thing with callbacks, then what's the point other then to be perhaps a little more readable?
