Most of these status updates shared news, reports and prayers. For some, Facebook provided a way to quickly get in touch with loved ones in devastated areas.
In the aftermath, the conversation continues as people post news and spread word about ways -- including using Facebook -- to aid the victims. A partnership between Zynga, Facebook and Save the Children allows users to donate money through the purchase of virtual goods in Zynga games. Users can also donate to either the American Red Cross or Save the Children's relief efforts using Facebook causes.
