Hey, this is a really good article, and I can attest to the topness of many of these folks personally:
Ellen Miller directs Sunlight Foundation, which is a really big deal. Sunlight leads the effort toward transparency in government, funding a network of sites which bring government info into the light.
Others include Vivek Kundra who taken a leadership role in really using new tech for better customer service for government, and Julius Genachowski, a leader in tech policy in Washington. Susan Crawford is a genuine leader regarding tech policy and law. Finally, Sascha Meinrath is part of the New America Foundation, genuinely respected as as a policy leader in municipal broadband networks and net neutrality.
All five are really big deals.
