I got the book and it's pretty good. It's nice to hear some stuff "straight from the horse's mouth" if you know what I mean. There is tons of great info on this web site, but sometimes it is just word of mouth stuff, so hearing something straight from the Big Man is a bit reassuring.
Good info in there about interviews -- little details about what to wear, etc...stuff you may not have thought much about.
I thought it was worth the $24.
