The concepts are mostly very good. I'm surprised that the author recommends Thesis as a theme framework, given that he's quite clear on the fact that themes and plugins should work with WordPress's core functions and hooks when possible; I wonder how closely he's really looked at this particular framework. The rest of his recommendations are good, and he mentioned a few useful-looking plugins I hadn't seen before.
Alas, reading this was really painful due to the basic linguistic errors. I hope the next time the author decides to self-publish, he either shells out for a cooyeditor or takes the time to learn to use "it's" correctly.
