Mira Sorvino.

If there’s one force that can affect social change, it’s a bunch of tech types ripped away from their computers and interfacing with one another. Inspired, perhaps, by the monumental leaps forward the TED conference has given our society, the Social Good Summit, presented by web concern Mashable, overlaps with the United Nations’s General Assembly in timing as well as some speakers. Former prime ministers of Poland and Norway, intellectual bon vivant Jeffrey Sachs and UN Goodwill Ambassadors Forest Whitaker and Mira Sorvino will all be addressing Mashable readers and other concerned citizens of the globe. Don’t worry if you can’t make it out today (Indian summer weekend on Fire Island?)—the conference continues tomorrow with Deepak Chopra and Ugly Betty’s America Ferrera.

Kaufmann Concert Hall, 92nd Street Y, 1395 Lexington Avenue, event runs Saturday through Monday, tickets and information can be found at socialgoodsummit2012.eventbrite.com.
