SoLoMo refers to social, local, and mobile technologies that combine geosocial networking and geolocation. These platforms allow users to check-in and share their locations, discover local businesses and events, and connect with other users nearby. Popular examples include Foursquare, Facebook Places, and Groupon, which businesses can use to target promotions at local customers, build loyalty, and increase sales. However, challenges remain in motivating large portions of the population to participate and addressing privacy concerns.
