One of the authors is Seth Godin. He is an interesting character, he is the VP of Direct Marketing at YAHOO, he wrote another book called "Permission Marketing" which also all right (but a little hyper at times). The interesting part about Seth is his other books are about things like bridge, Disneyworld, Dieting, DOS, Poker, Wine, Marketing, lots of other "If you are Clueless" titles, even one called "E-Mail addresses of the rich and famous". So he has a lot of experience writing for a very diverse group of people. Any way I would rate this book a buy.
