http://www.ted.com Accepting his 2007 TED Prize, James Nachtwey talks about his decades as a photojournalist. A slideshow of his photos, beginning in 1981 in Northern Ireland, reveals two parallel themes in his work. First, as he says: "The frontlines of contemporary wars are right where people live." Street violence, famine, disease: he has photographed all these modern WMDs. Second, when a photo catches the world's attention, it can truly drive action and change. In his TED wish, he asks for help gaining access to a story that needs to be told, and developing a new, digital way to show these photos to the world. (Recorded March 2007 in Monterey, CA.

At TEDU 2009, Erik Hersman presents the remarkable story of Ushahidi, a GoogleMap mashup that allowed Kenyans to report and track violence via cell phone texts following the 2008 elections, and has evolved to continue saving lives in other countries.
