Chris Hughes, the 26-year-old co-founder of social networking heavyweight website Facebook.com, is moving on to his next endeavour, this time with an eye on social justice. Today he announced a new website called Jumo.com, which means “together in concert” in the African tongue of Yoruba. The social networking website will connect people and organization with philanthropic and volunteerism in mind. Hughes, who also worked on Barack Obama’s presidential campaign, developed Jumo after travelling for a year through Senegal and Kenya. The website will officially launch this fall.
