I have written here before about Facebook privacy issues. It seems that Facebook likes to change the way your information is displayed and who can see it. It’s an issue you want to stay on top of. To assist with that, check out the free Facebook Privacy Checker.
To use this tool, go to www.reclaimprivacy.org and follow the directions on the front page.
When I checked my settings, I found that some information about me was available for anyone to see. The information in question was not critical, so I left it as is. But the important thing is that you are aware of what is out there so that you can control it.
