In 1998 Rick Levine, Christopher Locke, Doc Searles and David Weinberger published the Cluetrain Manifesto containing 95 theses, presumably, and possibly grandiosely, in the tradition of Martin Luther.
The manifesto was first published online, followed in December 1999 by a printed book issued by Perseus Books in Cambridge, Massachusetts.
