"Educators Advised to Be Cautious on Facebook Profiles"

With the popularity of social networking sites (per the video "The Social Media Revolution" we watched in Ed Tech, Facebook has 500 million people registered) this article doesn't surprise me in the slightest.  I would imagine this is an obvious precaution, since everything you post can be viewed by virtually anyone, but I guess the warning still needs to be broadcast.  While it may not be fair that teachers have to remain a notch or three above the bar when it comes to discretion, this is an intelligent outlook for anyone.  Posting on Facebook (or Twitter, or any other site) is akin to shouting from a rooftop - with a megaphone that will reach across nations.  Plenty of individuals have gotten in trouble at work, with the law, and of course their personal lives with their party pics and insensitive remarks.  It is important for parents to know the people their children spend the majority of their waking hours with are intelligent, caring and above all adhere to similar moral standards.  As a parent myself, I don't disagree.
