Given that this book was heavily advertised to make it a best seller, referring to his ideas as a global movement in startups is very superficial. What I disliked most about the book is that it’s not lean, if you think of the book as a movie, you’d be better of just by watching the trailer that highlights the best parts, which is his advertorial guest post that appeared on TechCrunch on the day the book was released.
