I've heard it's a bunch of pictures from the blog--no new material. Don't know if that's the case, and even if it is, it's probably still cool. I'll be interested to hear what anyone has to say about it.
Yup, I bought the book and I love it. :) I remember seeing some of the pics online before but I like being able to really look at them closely and have them at hand whenever I feel like leafing through the pages.
It's also really interesting to read Scott Schuman's own comments on some of the pics, about the situation in which he took the photo or his thoughts on how people reacted to the pic in the blog.
