Excerpt: " The Taiwan Society of Emergency Medicine has been in slow-moving negotiation with the Department of Health for the past several years over an appropriate solution to emergency-room overcrowding. A turning point was reached on Feb 8, 2011, when an emergency physician who was an active social network user and popular blogger among the emergency-room staff created a Facebook group called "Rescue the emergency room". Within a week about 1500 people -- most of the emergency department staff around Taiwan -- became members of this group and started discussing actively and sharing their experiences..."
