Over on TheSocialNetworker , there is a small series of screencasts showing off some Facebook Privacy checking tools.  With the recent changes Facebook  is providing at a whim, it is worth knowing what information you and your kids are showing to the world.  If you are currently unaware, a quick search would show numerous articles for your reading pleasure dealing in all parts of the comments from Mark Zuckerberg (founder of Facebook) and overall commentary from the industry.  Some ones I suggest:

• Mashable – Facebook and Privacy : It’s Time to Move On
• Mashable – Facebook’s Changes in Zuckerberg’s Words
• ReadWriteWeb – Facebook Privacy Briefing
• or just search for even more…

Be just as careful when loading these tools and applications to make sure they are legitimate.  The screencasts will wlk you through what they do, how they access the data and if they provide a service for you.
