The Cluetrain Manifesto began as a Web site (cluetrain.com) in 1999 when the authors, who have worked variously at IBM, Sun Microsystems, the Linux Journal , and NPR, posted 95 theses about the new reality of the networked marketplace.

For example, thesis no. 2: Markets consist of human beings, not demographic sectors”; thesis no. 20: Companies need to realize their markets are often laughing.

With a new introduction and chapters by the authors, and commentary by Jake McKee, JP Rangaswami, and Dan Gillmor, this book is essential reading for anybody interested in the Internet and e-commerce, and is especially vital for businesses navigating the topography of the wired marketplace.
