Ivan Sigal on Global Voices and the Arab Spring

The Arab Spring caught a lot of people by surprise, but not a group called Global Voices. It's made up of more than 300 bloggers and translators around the world who are closely watching Facebook, Twitter, YouTube and blogs, ready to report when ordinary people become citizen journalists, as they did throughout the events of the Arab Spring. Ivan Sigal, Global Voices' Executive Director, tells Anne Strainchamps about it.
