Social+Networking+Sites

Since the beginning of the 21st century, social network sites have taken the world by storm. Examples of these sites include myspace and facebook. MySpace, with 70 million visitors allows teens to chat and share pictures and websites. These sites allow users to upload profile pictures, add interests, music, and rate their friends. But what does the future hold for these sites? Social networking sites in general rely on simple advertising models -- selling banner and text ads. However, companies are predicting the user rate drops in the next few years. For more information see http://knowledge.wharton.upenn.edu/article.cfm?articleid=1463
