The Cluetrain Manifesto was one of the seminal books of the dot.com bubble era, but reading it now is like waking with a hangover and looking at all of the empty bottles, each of which seemed like a great idea at the time. The Internet changed everything, all right. Those who can bite back the irony long enough to see the big picture and keep reading will find some valuable practical advice on using the now-not-so-new-technology of the Web to do business more effectively. We recommend this pivotal book for the sake of your sense of perspective (or to give you a critically necessary background if you are too young to remember when Amazon was just a river.)
