I just finished David Kirkpatrick's The Facebook Effect: The Inside Story of the Company That is Connecting the World," and highly recommend it. It is the best book I have read to present the fascinating inside story of Facebook, its remarkable founder and team and to place Facebook in the context of the ever evolving and transforming world of the Internet. David also presents one of the best discussions I have read on the difference between Google with its emphasis on computers and the organizing the world's information and Facebook, with its focus on people and the sharing of information through the "social graph", your personal network of friends, family and colleagues. That differences is not just about finding the best place to buy a camera, but in rethinking how we navigate the online world.
David, a fine and experienced industry veteran, is a senior technology writer for Fortune Magazine, and I had the priviledge of working with him many years ago on the same high tech conference. If you haven't already read it, I highly recommend you do so.
