App as parent-child talking point

Here's a good talking point for the tech part of parenting: Facebook Grader. It's a mini application ("app") that tells users their "reach and authority" on Facebook, TechCrunch.com reports. "The tool works by analyzing the number of friends you have, how important those friends are (whatever that means [maybe based on how many "friends" on their lists?]), how complete your profile is, how many wall posts you have and how many groups you belong to." Billed as a profile grader, for some kids it may be more of an indicator of how cool, sought-after, or popular they are. So it could fuel a discussion about whether your child uses a grading or rating tool like this, what s/he likes about social-networking, what it's best for, whether something like Facebook Grader is really any indicator of what a good person s/he is, and what s/he feels (and you feel) the real indicators are or should be.
