You know a book is good when you can breeze through it in a day. Of course, it helps that I spent half the day flying on airplanes - and that they've relaxed the electronics rule, so I could read from the gate to 10,000 feet (at which point I pulled out the laptop to do some ACTUAL work).

The book is more a commentary on the current state of social networking including several things George has learned from his stint in the Twittersphere and, more recently, Facebook.
