Say what you will about Guy, he's a hell of a speaker. His "Art of the Start" video should be required viewing for everyone everywhere with even a passing interest in startups or public speaking. It's very compelling stuff.
I picked up his book, Art of the Start, a few weeks ago and was somewhat disappointed. I love Guy, except that Garage invested in Gator/Claira, and read his blog and watch his speeches. After that there really was nothing new in the book.
