As a side note, I'd like to point out that a lot of scam books appeared on amazon in the marketing and startup sections lately. The worst thing, they all got fake 5 star reviews, so it's not always clear right away this is a scam.
Btw, the fact that you suggested that book made me understand how much the current way Amazon suggest you books doesn't really take in consideration your goals or background.
It should actually ask you "Why are you buying this book?" Me "Because I want to make a startup" AMZ "Oh cool, what's you background?" Me "I am hacker" AMZ "Oh ok then with Seth Godin you are going a little bit too businessy. Try Start Small, Stay Small"
