Foursquare has seen increasing popularity as a location-based social network over the past 12 months. It now has over 16 million users and 25 million places worldwide. Brands and organizations are increasingly using Foursquare's brand pages and badges to market to users, with over 5000 brand pages now on the platform. While adoption is still low among businesses, Foursquare provides an opportunity for passive customer engagement without disrupting daily routines.
