I had high hopes for this book, but ended up being disappointed by it. First, it's very short (a hundred tiny pages), and feels more like a long survey article than a real book. A big chunk of the book is taken up by vague, trite observations about how the web is changing various things; these are familiar to everyone with the slightest interest in technology. The core of the book has very little detail. For example, one part deals with power laws in various statistics for the web. I knew the book was aimed at a non-technical audience, so I didn't expect any mathematical or scientific detail in this part of it, but I was hoping for a broad, motivated survey, that would discuss the history of power laws, where they appear and what they mean, how they were discovered here, etc. Instead, we get a couple of paragraphs that vaguely mention earthquake sizes and barely touch on the history (e.g., Zipf, Mandelbrot). Huberman does go into more detail in some aspects of power laws, like a discussion of toy models of the internet and which ones exhibit power laws (vs. log-normal distributions, say). However, I really don't see what audience he is aiming at. A technical audience could read something much more sophisticated, and I'm not sure why a non-technical audience would care about which toy models show which distributions, if the history and meaning hasn't been explained to them. Overall, I don't think most people will get much out of reading this book (although it does have the merit that it can easily be read in one sitting). It's kind of sad that some readers will probably be very pleased by Huberman's breathless descriptions of how interesting and important various things are, and will never realize that, if he had written a longer, more detailed book, they could have achieved a much deeper and more satisfying understanding. (Telling someone how great something is is never as good as showing them.)
One final comment is that much of the work in this book is Huberman's own. I tend to think he wrote it as a short advertisement for his papers. His work is indeed important, but lots of other people have done related things. Perhaps someday someone will write a broader book that puts the whole field in proper perspective.
