From the Wall Street Journal:
Americans may not agree on much, but here's one point of consensus: Social media isn't entirely wonderful. Facebook has its privacy scandals, and who would join Twitter for the camaraderie? This week an ugly online mob demonstrated the point by setting upon a group of boys on a field trip to Washington from Kentucky's Covington Catholic High School.
"Because I don't have any social-media accounts," says Cal Newport, a Georgetown University computer scientist, "my encounter with the Covington Catholic controversy was much different than most people's." He read about it days later, in a newspaper column. "I learned that the social-media reaction had been incendiary and basically everyone was now upset at each other, at themselves, at technology itself. It sounded exhausting."
Mr. Newport, 36, appreciated the downsides of social media sooner than most. In 2010 he published "An Argument for Quitting Facebook," a blog post that came with a graphic of the "deactivate account" function on an amusingly out-of-date Facebook version. "Technologies are great," he wrote, "but if you want to keep control of your time and attention," you should "insist that they earn their keep before you make them a regular part of your life." He has been proselytizing against social media ever since. His book on the subject, "Digital Minimalism: Choosing a Focused Life in a Noisy World," hits stores (and e-readers) next month.
