When you Don't Want to be Facebook Friends:
Social networking sites such as Facebook have experienced phenomenal growth in the past year, according to market researcher comScore. Facebook is now the No. 1 social networking site, with more than 120 million active users, and its fastest growing demographic is those 25 and older.
