Ethan Zuckerman is one of the big thinkers, and doers who consistently inspires me. His Wikipedia entry identifies him as “an American media scholar, blogger, and internet activist.” All of this is true, but that’s just part of the picture. He’s also someone who consults regularly with major foundations, think tanks, NGOs, and policy-makers, as they try to understand the potentials, and risks, of networked computing. As the founder of GeekCorps and Global Voices, he’s put his geeky skills to work to try to change the problems which worry him the most about our contemporary culture. He’s someone who has a formed a network of other bloggers and digital activists around the world, and someone who travels often to parts of the planet that most of us could not point out on a map, in order to better understand the political, cultural, and technological conditions on the ground there. He’s become one of our best thinkers about “digital age civics” and through his work as the Director of the MIT Center for Civic Media, he’s leading a team of graduate students as they seek to design tools which might empower activists and community leaders to be more effective at fostering social change. He does this while remaining mild-mannered, easy-going, modest, and open-minded, a model for what an engaged public intellectual might look like in the 21st century. I am lucky to be able to call him a friend.
