PBS’s FRONTLINE/World has launched the first edition of iWitness, a new feature that connects with people around the world to tell important stories. With regular reporters as well as ” activists and artists, doctors and teachers, even avatars reporting from virtual communities, such as Second Life,” iWitness promises to bring interesting insights to top stories. Currently featured: videos on the riots in South Africa, and an account by Washington Post video journalist Travis Fox on covering the earthquake in China. Definitely a site worth bookmarking and coming back to.
