Social network service

From Computing and Software Wiki

SNS (Social Network Service) is the application service that helps people builds online social communities where they share interests and/or activities. Most SNSs are web based to provide a variety of ways for users to communicate or interact, such as social network websites, e-mail, SMS (short message service), and blogs. The idea of SNS is based on the concept of “Six degrees of separation” which introduced by Stanley Milgram, the social psychologist at Harvard University. Simply say that “if a person is one step away from each person they know and two steps away from each person who is known by one of the people they know, then everyone is at most six steps away from any other person on Earth.”[1]
