A social networking service (also social networking site, SNS or social media) is an online platform that people use to build social networks or social relations with other people who share similar personal or career interests, activities, backgrounds or real-life connections.
The variety of stand-alone and built-in social networking services currently available online introduces challenges of definition; however, some common features exist: (such as former school-year or classmates), means to connect with friends (usually with self-description pages), and a recommendation system linked to trust.
