Virtual Volunteers Use Twitter And Facebook To Make Maps Of Nepal

The village of Melamchighyang needs 100 blankets. The remote area of Hyolmo has many injuries, and only two nonprofit groups are providing "limited aid." Two girls from Germany are missing in Langlang Valley. People are stranded in Kyanjin Gompa. These pleas for help in the aftermath of the Nepal earthquake have popped up on ever changing maps of the disaster zone, compiled and posted by hundreds of digital volunteers around the globe.
