I may have missed something, but this doesn't feel like a review, it feels like he's rehashed and summarized every point in the book without adding any original content, beyond how he's been using the techniques. A nice glowing review with some choice summaries would have been plenty to get me to dig deeper and purchase the original book. After reading this though, I feel I've pretty much gotten everything I could have from the book and have no desire to actually purchase it, beyond supporting the original author. I enjoyed the material, and I think it's going to be really useful going forward, but maybe a Spoiler Alert warning would have been appropriate.
