It's super-fun to read a non-fiction book so close to the release date, and hence so up-to-date, as this is right now. There are no big revelations, but the writing is interesting, well-researched, and relevant enough that it just kept pulling me in. It's a short book, too -- the last 50 pages or so are notes.
Google is a Big Deal, and even though there's not much more to say then "we really should be keeping an eye on these folks," this book is valuable.
Also, it'll probably be completely irrelevant in six months.
