Researchers believe they have unraveled the Holy Grail for why social
network sites are so popular. The findings help to explain why one
particular site has become a world-wide sensation with a targeted subset of its 845 million users and an estimated net worth of between $75 and $100 billion dollars.
The key to popularity of social networking sites (SNSs) revolves around how the experience makes us feel. Investigators discovered social networking sites such as Facebook and MySpace evoke a positive experience on individuals when the users access and use the sites.
