Grandma 'friended' me: Facebook users getting older fast

Funny how only a few years ago you were hearing about this new-fangled Facebook thing and how it was taking college campuses by storm. Sorry, junior. Grandpa's taking over. According to interactive research and buzz-tracking agency iStrategy, the fastest growing segment of Facebook in the month of July was users who are 55+. (The highly curious can download a spreadsheet of the findings here). That's a stunning finding but it validates what I'd been hearing from a number of teens and college kids who had been "friended" not only by their parents, but sometimes by their own grandparents on Facebook.
