US Embassy Joins Facebook To Boost Links

Facebook is a popular social networking website that is accessible free of charge. It is an interactive social communication tool used by students at secondary school, college, university and government corporate and private sector employees.

According to the Wikipedia, a social network is a "social structure made of individuals (or organisations) called "nodes," which are tied (connected) by one or more specific types of interdependency, such as friendship, kinship, financial exchange, dislike, sexual relationships, or relationships of beliefs, knowledge or prestige," it says in part.
