Underage and on Facebook

FACEBOOK'S minimum age should be 21. This argument mooted by CNN blogger John D. Sutter will no doubt get the support of many parents who worry about safety and privacy issues on the social media network. That is, those parents who have not secretly signed up, or helped to sign up, their children on Facebook.
