Today in Mobile

My former colleague Liz Gannes reported this morning that Foursquare and Groupon are in negotiations to deliver a service that would offer deals to users when they check in. The partnership is a natural fit for both players, giving Groupon fertile soil to expand its business to mobile and providing a real incentive for Foursquare users to broadcast their whereabouts. I think the novelty factor of check-ins is beginning to wear thin with many users, but receiving great deals for doing so will eventually provide a huge lift to the mobile/local/social space.
