Soon, more windows will be broken, and the sense of anarchy will spread from the building to the street on which it faces, sending a signal that anything goes.

Horchow's daughter, Sally, told me a story of how she once took her father to a new Japanese restaurant where a friend of hers was a chef. Horchow liked the food, and so when he went home he turned on his computer, pulled up the names of acquaintances who lived nearby, and faxed them notes telling them of a wonderful new restaurant he had discovered and that they should try it.

Word of mouth begins when somewhere along that chain, someone tells a person like Roger Horchow.
