Useful utility, could use more documentation – S.N.A.P. Review

After some difficulty getting logged in to Facebook (assuming that is API related on Facebook's part?) I was able to check my grade in a number of areas. I would like to have more information on how the grade was derived, and what specifically I can do to change the grade (higher or lower). Given Facebook's rather constant re-writing of their privacy policy, this app is one that will let you know what degree of exposure your personal information has. Scary thing is - most people won't ever go beyond the default FB settings - hoping this app helps educate people how risky that can be.
