If you want to find somebody who thinks they're better than you, it's easy — just find someone who voluntarily left Facebook. (Also, I don't know why you would want to find someone who thinks they're better than you, but if you do, you might want to see a therapist about your self-esteem issues.)
In this new video, the fine folks at College Humor do a great job at illustrating the self-importance of people who choose to leave Facebook. And if you're thinking of leaving Facebook, I have this message for you: I strongly support you in your decision to live more in the real world, and you definitely do not need to tell me about it.
