The arrests of more than 700 people on Saturday as thousands tried to cross the Brooklyn Bridge seemed to pour oil on the rage of those who camped out overnight in Zuccotti Park, a private plaza off Broadway near Wall Street.

“We don’t care whether mainstream media covers this or people see us on television. What counts are the more than 30,000 viewers following our online live stream,” he said. “We heard from a lot of them, and they’re joining us now!”

The Occupy Wall Street demonstration started out last month with fewer than a dozen college students spending days and nights in Zuccotti Park. It has grown significantly, both in New York City and elsewhere as people across the country, from Boston to Los Angeles, display their solidarity in similar protests.
