“These movements are significantly different from the good old ‘marchas,’ ” said Andrés Monroy-Hernández, a fellow at Harvard’s Berkman Center for Internet and Society. “The stereotype of the marchas was that they were movements made up of working-class folk, led by charismatic union or political leaders. These new social media movements seem to be structurally different: they are networked, and attract a different demographic — middle-class youth who probably identify more strongly with Occupy Wall Street and the Arab Spring.”
