ABSTRACT
In Seoul, a young woman uses the location-based social networking service Kakao in order to tag, upload, and share a photo just taken of their catch-up with friends. In Helsinki, a family plays Angry Birds together, as the app gathers information on their location via the smartphone and its location technologies and sensors. In Chongqing, middle-class café habitués are sharing contacts, messages, and photos via the networking application Jiepang (which now includes the trendy mobile app WeChat), popularized in cities like Shanghai. In rural United States, a child calls 911 emergency services for help, and the ambulance is dispatched using the location information available via their absent parents’ phone.
