So far, 20,000 of Foursquare’s four million users have the “I Voted” badge, reports Brenna Ehrlich at Mashable.

Foursquare is allowing users to earn a digital “I Voted” sticker today by checking in at their local polling places and adding “#ivoted” to their shouts.
Organizations such as Rock the Vote, Pew Center, Google and the Voting Information Project have partnered with Foursquare to make this badge possible at over 100,000 polling places.
