it's a perfectly normal book, although you get the odd funny look if you sit in a cafe reading a book with the word "BLOOD" emblazoned across the top of the front cover. I think all the "posts" in the book are also in the blog, but there's little bits before and/or after some posts saying how things turned out, or what kind of comments it got, that sort of thing. I seem to recall Tom describing these as like the commentary on a DVD's "extras" section.
