New York CNN  — 

A spirited and leaderless protest in the Wall Street section of New York has entered its third week, helping to inspire a growing number of demonstrations united in their passion if not necessarily their reasons for hitting the streets.

The hub of the movement, in Lower Manhattan, was abuzz with activity on Sunday as activists continued to vent their frustrations with everything from “corporate greed” to high gas prices to insufficient health insurance.
