MacRuby: The Definitive Guide

I wonder how Matt feels about getting feedback in this way, apart from the open licensing. So many of the comments seem superficial (something a good copyeditor might simply fix, later in the process). He seems to be a good sport in responding, though.

And will his developmental editor at O'Reilly use this interface? Or can public scrutiny stand in for editorial oversight, and the 'true' editing will be minimal? Perhaps a new model for book publishers.

Is there a post mortem written anywhere by authors who have used a public commenting feedback system like this (The Django Book, Real World Haskell, among others)? I'm curious if it would be helpful or mostly annoying to authors.

I wonder if the commenting system itself encourages trivial, nitpicky corrections rather than big picture feedback.
