Groupon (GRPN) has made another acquisition, buying semi-popular location-tracking app Glassmap for an undisclosed sum. Glassmap works a bit like Google Latitude, allowing users to track the location of and message Facebook "friends" who have also signed up for the service in real-time, as well as keep tabs on Facebook/Twitter feed updates. Groupon could conceivably use Glassmap's tech to deliver a service that alerts mobile users to nearby deals. (CommerceInterface)
