I love the gid-scribe idea, I am learning backbone atm and one of the problems is the changes in 0.5.0 seem to put lots of old resources out of whack by a few degrees.

I think resources should be paid for (I just bought the peepcode videos from a comment here) I would be mildly worried that $49 might be a little high for some, but then again I hope I am wrong. Previews are always nice to see, the first couple of chapters to get a feel.
