CNET NEWS - Jan 29 - Foursquare is a consumer-facing app that people use to share their whereabouts with friends and to discover new places to go. The new business app, available today on iPhone and Android, is an extension of Foursquare's long-standing merchant dashboard and is meant to provide venue owners with a window to what's happening at their stores. The app allows merchants to view recent checkins and posts at their venues, check out top customers, and turn their specials on or off.
