Friday, we discussed Occupy Wall Street and asked if two weeks of protests by a few hundred people might escalate into something more. Over the weekend, groups settled down outside City Hall in Los Angeles and planned to snarl rush-hour traffic in Chicago and Boston. They also appear to have found a central message. "We are the 99 percent" is a slogan now being repeated by protesters in several cities and circulated on the Internet, where the Tumbler blog shows pictures of hand written explanations. Nate Rawlings is covering the story for Time magazine.
