I was living here in Manila during Typhoon Ketsana (September 2009) and was impressed by how Facebook and Twitter quickly became the most reliable and most-used sources for information. "The evacuation center in Mandaluyong needs diapers"; "Volunteers meet at Ateneo, 6am"; "Can someone in Marikina check on Maria Navarro and family? Haven't heard from her yet. Address: …"; "I am collecting food, does anyone have a truck?"
