Social networking is big driver on web

Social networking sites are the hottest attraction on the Internet, dethroning pornography and highlighting a major change in how people communicate, according to Bill Tancer, a self-described "data geek." He's analyzed information for over 10 million web users to conclude that we are, in fact, what we click, with Internet searches giving an up-to-date view of how society and people are changing. Some of his findings are great trivia, such as the fact that elbows, belly button lint and ceiling fans are on the list of people's top fears alongside social intimacy and rejection. Others give an indication of people's interests or emotions, with an annual spike in searches for anti-depression drugs around Thanksgiving time in the United States.
