Global Voices Swahili
Global Voices is an international community of writers, bloggers and digital activists that aim to translate and report on what is being said in citizen media worldwide. It is a non-profit project started at the Berkman Center for Internet and Society at Harvard Law School that grew out of an international bloggers' meeting held in December 2004. The organization was founded by Ethan Zuckerman and Rebecca MacKinnon. In 2008, it became an independent non-profit incorporated in Amsterdam, Netherlands.
