The best reason to quit Facebook can be summed up in one quote from a 29-year-old in Jenna Wortham's latest item in The New York Times: "People always raise an eyebrow. But my life has gone on just fine without it." Like a lot of Times trend pieces, people have been talking about this phenomenon for ages. But Wortham's news peg is startling. Citing comScore Wortham reports that Facebook is continuing to grow in the United States, but after a 56 percent boost from October 2009 to October 2010, Facebook grew only ten percent from October 2010 to October of this year. Why? Well, Wortham gives a lot of reasons, quoting experts and so forth. But it's all very clear to us. To wear out that worn out Social Network quote a bit more: Joining Facebook isn't cool. You know what's cool? Quitting Facebook.
