Too Much Facebook?

Chicago Tribune article entitled "Too Much Facebook Time May Be Unhealthy for Kids." The article reviews recent research presented at the 2011 American Psychological Association that reveals children who use more technology are subject to a number of emotional and physical issues (e.g., anxiety, depression, sleeping problems, stomach aches), as well as have increased feelings of narcissism. They also find technology-savvy children have much shorter attention spans. Is social media bad for children? Should parents be limiting technology time, or just monitoring it? What impact does technology have on cognitive, emotional and physical development in the long-term?
