Facebook co-founder Chris Hughes -- yes, he is featured as a pivotal character in The Social Network movie -- is up to something new.

His startup, Jumo -- a philanthropic endeavor that works to match people with political movements, nonprofit organizations and other causes -- formally launched today. (Jumo means "together in concert" in Yoruba, a West African language.)

Hughes, who spearheaded My.BarackObama.com, the organizing online platforms for the Obama presidential campaign, says the site's mission is simple.
