Do the names MySpace, Facebook, Orkut, etc. ring a bell? They probably do because they are some of the most popular sites on the internet today. These sites are all called 'social networking' sites because they help people meet and discuss things online. Each of these social networking sites has its own strengths: MySpace is especially popular among teenagers, Facebook is popular with college age people, Orkut is especially loved in Brazil, and CyWorld is the site to visit in South Korea. The common thread between all of these social networks is that they provide a place for people to interact, rather than a place to go to read or listen to 'content'.
