Being popular on Facebook might mean you're really a jerk

If you have a staggering number of Facebook friends, chances are you're also probably a "socially disruptive" narcissist. At least that's the word from a study published in the Personality and Individual Differences journal, which reveals that people who achieved a high score (yay!) on the Narcissistic Personality Inventory questionnaire (ummm...) "had more friends on Facebook, tagged themselves more often and updated their newsfeeds more regularly." Users with egos in overdrive also tend to change their profile pictures more often and respond more aggressively to derogatory comments. However, if you still feel an overwhelming urge to friend every person you've known since nursery school, there are plenty of how-to videos on YouTube that can help boost your numbers.
