Wall Street protest spreads to Boston

CNN reports that a Twitter account called Occupy Boston is calling for a city wide college and university walkout today. The Massachusetts Nurses Association says it will participate.
Some observers say that the movement's strength rests in the fact that it is leaderless. Economic issues and chronic high unemployment appear to be the major propellants -- "liberal economic populism, a powerful force in U.S. history during times characterized by economic stress," opines the CNN analysis.
New York activists are camping out in parks as Occupy Wall Street enters its third week. Social media is playing a significant role in the demonstrations.
