Could a Facebook competition encourage users to cut their utility usage? Can a mobile communication network help rural farmers share crop tips? Bringing together activists, world leaders and tech influencers, the second annual Social Good Summit seeks to answer these questions and more.

The summit, which kicked off on Monday in New York, aims to find new ways to use new media and technology to make the world a better place.
