Warning to parents: Kids are learning about sex on YouTube

Children used to learn about sex on the street – either from friends, those weird older kids who'd smoke behind the dumpster, or a friend's older and ostensibly wiser sibling. Web 2.0, of course, has changed all this. Instead of getting the goods from an unreliable source in person, a recent study suggests that kids are turning to the likes of YouTube, Google (GOOG) and Facebook, among others.

The study, conducted by technology security company Symantec (SYMC), puts expressions such as "sex" and "porn" at the top of search lists.
