It's all about me

A Facebook page might tell more about its owner than people realize.

If you're a narcissist — a vain, self-promoting sort with illusions of undeserved grandeur — you're likely to show it in your Facebook profile, according to a new study conducted in part by University of Kentucky psychology professor Nathan DeWall.

The study shows that narcissists tend to display more self-promoting and sexy images, even as they use fewer first-person singular pronouns, such as "I" and "me." Some narcissists also use profane and aggressive words to call attention to themselves online.
