Answer to Question 2

Geosocial services help you find friends, or your friends to find you, by checking in to the service and announcing your presence in a restaurant or other place. Your friends are instantly notified. About 20 percent of smartphone owners use geosocial services. One example of a firm using geosocial services is Foursquare. Foursquare provides a location-based social networking service to 55 million registered individual users who may connect with friends, update their location, and provide reviews and tips for enjoying a location. Points are awarded for checking in at designated venues. Users choose to post their check-ins on their accounts on Twitter, Facebook, or both. Users also earn badges by checking in at locations with certain tags, for check-in frequency or for the time of check-in. More than 500,000 local merchants worldwide use the merchant platform for marketing.
