Don't let the (literally) clueless title turn you off. This is an impressive tour de force. The first half is a concise, entertaining, and enormously informative history of technology and its effects on our social customs and ways of looking at the world. Lane's grasp of mountains of material and his ability to concisely summarize it are awesome. Since I am in a related field, I intended to skim it, but was drawn into reading every word. The second half is more specialized, but is only tangentially devoted to "obscene profits" (that awful title looks like a publicists's handiwork). It poignantly conveys the ways the new technology reveals for the first time that men's obsession with pornography is of epidemic proportions.
