A friend of mine just sent me a link to this website. It is a free, open source tool that scans your Facebook account and gives you feedback about how private it is. It only takes about 15 seconds to run it, and it is super easy to use. Go ahead and try it - see how private your page is. The results will also then take you to the privacy settings so you can see what is open to "everyone".
