AN ARMY OF HAOS:

A busload of volunteers in matching red hats was bumping along the village’s rutted dirt road. Employees from a private company in Chengdu were cleaning up a town around the bend. Other volunteers from around China had already delivered food, water and sympathy.

“I haven’t done this before,” said Mr. Hao, 36, as he straddled his mountain bike on Saturday evening. “Ordinary people now understand how to take action on their own.”

Private initiative in disaster relief. Self-organization by ordinary people. Somebody should write a book on this stuff.
