In a new civic participation project for the 2010 midterm elections, Foursquare will provide an ‘I Voted” badge for those who check in at their local polling place.
Working with groups such as MTV’s Rock the Vote, the Pew Research Center, Google and the Voting Information Project, Foursquare has gathered location information for 107,000 polling places. Adam Ostrow reports that users who check in and use the “#ivoted” hashtag will receive the badge. A special elections site created by Foursquare will track the activity on an interactive, real-time map.
