Ninth graders at Wakefield High School in Arlington, Virginia, were greeted by some social networking advice from President Obama on Tuesday. He advised them to not let their guard down on social networking sites such as Facebook, for the ghosts of their gay abandon could come back to haunt them later.

“I want everybody here to be careful about what you post on Facebook,” Obama told a group of 40 ninth graders. “Because in the YouTube age, whatever you do, it will be pulled up again later somewhere in your life. And when you’re young, you make mistakes and you do some stupid stuff. ”

Recent studies have shown that an increasing number of hiring managers closely examine the social networking profiles of job candidates. So, a bit of caution on the part of these kids will at least ensure that they don’t remain unemployed because of social networking gaffes.
