Spend your time looking at how personal Facebook can get.

In the "Lifestyle and culture" section, Facebook gets personal. It tells you all these facts it thinks about you. For example, it thinks it knows I live away from my hometown, that my political views lean liberal, that I use Gmail and Google Chrome, and other tidbits.

Don't forget to remove advertisers that have your information as well.

In the "Advertisers" section, you can see two groups: advertisers that have your contact information and those "whose ads you may see because you visited their website or app that uses Facebook technology." To remove them, hover your mouse over the icon and tap the "X" in the top right corner.
