A social networking service is an online service, platform, or site that focuses on building and reflecting of social networks or social relations among people, e.g., who share interests and/or activities.A social network service essentially consists of a representation of each user (often a profile), his/her social links, and a variety of additional services.Most social network services are web based and provide means for users to interact over the internet, such as e-mail and instant messaging.Online community services are sometimes considered as a social network service, though in a broader sense, social network service usually means an individual-centered service whereas online community services are group-centered.Social networking sites allow users to share ideas, activities, events, and interests within their individual networks.
