I came across Ushahidi on one my favorite blogs. Ushahidi, which means "testimony" in Swahili, has an amazing objective: it allows people all over the world to tell others about what is happening to them or around them. Originally created after the Kenyan uprisings after the election in 2008, Ushahidi has since covered the Snowmaggedon in D.C., the aftermath of the Chile and Haiti earthquakes, and numerous other crises across the world. It even links survivors of human trafficking.
Remarkable!
