Unfriended on Facebook? You're Probably Boring

It's the all-important question of our age: Why have I been unfriended?! A doctoral candidate at the University of Colorado Denver Business School surveyed 1,500 Facebook users to find out and concluded that the No. 1 reason is ... endless boring, unimportant messages. Or, as researcher Christopher Sibona puts it: “The 100th post about your favorite band is no longer interesting.”

Not surprisingly, polarizing posts—such as those about religion or politics as well as crude or racist remarks—also result in unfriending. And more than a quarter of those surveyed say they got unfriended in the virtual world for something they did in the real world.
