Wall Street Protesters More Savvy Than Sloppy

Occupy Wall Street protests are planned in cities around the country Saturday. On Friday in New York, a planned clean-up of Zuccotti Park near Wall Street was postponed. NPR's Margot Adler reports on daily life in the Lower Manhattan park where the protest movement began. At first glance, the lives of the protesters may seem loose and anarchistic, but there's actually lot of invisible technology, infrastructure, innovation and even some sophisticated finance going on.
