Can an online algorithm track down your child?In some cases, yes — and if you’re a parent, it could alarm you too.Consider the case of Maggie Leifer McGary, mother, blogger and social media fan. Ms. McGary is on virtually every existing social network: Foursquare, LinkedIn, Twitter, Facebook. She is also on Klout, a popular site that assigns you a score based on its analysis of how influential you are on the social Web.In the days just before Halloween, Ms. McGary got the fright of her life when she checked her Klout profile.
