Reclaim (Facebook) Privacy
This bookmarklet by Matt Pizzimenti allows you to easily see which of your Facebook privacy settings might not be as secure as you think.
At first, I was skeptical about what might happen after logging into Facebook and clicking the bookmarklet (note: maybe there should be a demo video?), but everything seemed to check out just fine.

If you’ve spent quite a bit of time configuring your privacy settings through the recent Facebook updates, there shouldn’t be any surprises here; otherwise, I can see this being immensely useful for making sure you’re covered.
For more info, check Twitter (@reclaimprivacy) and/or the source code on Github.
