How parents can protect their kids online

With teens flocking to social media sites to express themselves and connect with friends out of school, some are learning all too well the dangers of letting it all hang out. Rochester High School in Springfield, IL, suspended some students from athletics and other extracurricular activities after they posted on Facebook pictures of themselves underage drinking.

Even President Barack Obama expressed concerns that teens were not doing enough to protect their privacy. In a meeting with students at Wakefield High School in Arlington, VA last September, he answered a question about how to become president with, "Well, let me give you some very practical tips. First of all, I want everybody here to be careful about what you post on Facebook, because in the YouTube age, whatever you do, it will be pulled up again later somewhere in your life."

He continued, "And when you're young, you make mistakes and you do some stupid stuff. And I've been hearing a lot about young people who -- you know, they're posting stuff on Facebook, and then suddenly they go apply for a job and somebody has done a search."
