Mark Zuckerberg's political wingman: Fwd.us founder Joe Green

Joe Green, Mark Zuckerberg's Harvard roommate, is famous for having turned down an offer to move to Silicon Valley to join Facebook.

Instead Green finished his college degree and worked for 2004 Democratic presidential nominee John Kerry, missing out on a once-in-a-lifetime payday. Now he's reuniting with his college pal on a project that straddles two worlds for which he has great affinity: technology and politics. Green, 29, is the founder and president of Fwd.us, a new political advocacy group funded by Zuckerberg and other prominent Silicon Valley executives to press for immigration reform and other technology industry causes. The group is the result of months of conversations between Zuckerberg and Green on how the technology industry can have a meaningful impact on the causes it cares about.
