I have to admit, I chuckled a bit after reading Protect Your Privacy: My Facebook Lesson Learned.
Thankfully, when I was an undergrad, we didn't have such worries. But, I can only imagine if we had. Young adults do some pretty silly things when they're out with friends. Of course, these things are not meant for employers, but that is the danger nowadays. You never know who might be recording your antics or snapping pics. So, do yourself a favor and read the article. My guess is that Mr. Smith might just have saved these college students some future angst come career time.
