Script Summary: Shows Wikipedia info for your interests when you hover over a link. Thanks to Jared Morgenstern for the idea.
FYI, I am no longer maintaining this script or anything linked to within it. It may not work anymore because of the changes that have been made to Facebook in the last couple years.
You can also view other sections by uncommenting some code. In order to do this, you need to have a saved copy of this script on your computer. In the future, there will be a cool user interface for deciding which sections to display data for.
