Wow, that is a truly huge number and a massive leap of achievement in only 5 years.
"For the first time, half of all adults in the United States said they used a social networking site, according to a survey released on Friday by the Pew Research Center.
That is 50 percent of all Americans, not just those who say they are online. Six years ago, when Pew first conducted a similar survey, only 5 percent of all adults said they used social sites, like Facebook, LinkedIn or MySpace."
