Social media present risks and benefits to children but parents who try to secretly monitor their kids' activities online are wasting their time, says Larry D. Rosen, Ph.D., professor of psychology at California State University, Dominguez Hills. Rosen identifies potential adverse effects of social media, including: Teens who use Facebook more often show more narcissistic tendencies, while young adults who have a strong Facebook presence show more signs of other psychological disorders, including antisocial behaviors, mania, and aggressive tendencies. Daily overuse of media and technology has a negative effect on the health of all children, especially preteens and teenagers, by making them more prone to anxiety, depression, and other psychological disorders, and making them more susceptible to future health problems. Facebook can be distracting and can negatively impact learning. Studies found that middle school, high school and college students who checked Facebook at least once during a 15-minute study period achieved lower grades. Rosen says new research has also found positive influences linked to social networking, including: Young adults who spend more time on Facebook are better at showing "virtual empathy" to their online friends. Online social networking can help introverted adolescents learn how to socialize. Social networking can provide tools for teaching in compelling ways that engage young students. "If you feel that you have to use some sort of computer program to surreptitiously monitor your child's social networking, you are wasting your time. Your child will find a workaround in a matter of minutes," he says. "You have to start talking about appropriate technology use early and often and build trust, so that when there is a problem, whether it is being bullied or seeing a disturbing image, your child will talk to you about it."

Speaking at LIFT 2007, Sugata Mitra talks about his Hole in the Wall project. Young kids in this project figured out how to use a PC on their own -- and then taught other kids. He asks, what else can children teach themselves?

On July 29th, returning from a trip to Europe, Jacob Appelbaum, a lanky, unassuming 27-year-old wearing a black T-shirt with the slogan "Be the trouble you want to see in the world," was detained at customs by a posse of federal agents. In an interrogation room at Newark Liberty airport, he was grilled about his role in Wikileaks, the whistle-blower group that has exposed the government's most closely guarded intelligence reports about the war in Afghanistan. The agents photocopied his receipts, seized three of his cellphones - he owns more than a dozen - and confiscated his computer. They informed him that he was under government surveillance. They questioned him about the trove of 91,000 classified military documents that Wikileaks had released the week before, a leak that Vietnam-era activist Daniel Ellsberg called "the largest unauthorized disclosure since the Pentagon Papers." They demanded to know where Julian Assange, the founder of Wikileaks, was hiding. They pressed him on his opinions about the wars in Afghanistan and Iraq. Appelbaum refused to answer. Finally, after three hours, he was released. Sex, Drugs, and the Biggest Cybercrime of All Time Appelbaum is the only known American member of Wikileaks and the leading evangelist for the software program that helped make the leak possible. In a sense, he's a bizarro version of Mark Zuckerberg: If Facebook's ambition is to "make the world more open and connected," Appelbaum has dedicated his life to fighting for anonymity and privacy. An anarchist street kid raised by a heroin- addict father, he dropped out of high school, taught himself the intricacies of code and developed a healthy paranoia along the way. "I don't want to live in a world where everyone is watched all the time," he says. "I want to be left alone as much as possible. I don't want a data trail to tell a story that isn't true." We have transferred our most intimate and personal information - our bank accounts, e-mails, photographs, ph
