Social networking sites are the best way to help people to know about friends and family. The geographical and cultural barriers were something very difficult to break down, but nowadays the problem has been solved. These sites provide people a tool for knowing about the friends and family, not only if they are far away but also if it is impossible to interact face to face in a short distance. For example, if there is some student learning a foreign language in another country, the communication with the family and friends, today can be able. The social networking is a very good option to keep in touch with others.
