C'mon, is your life really that interesting?

It's amazing what people will do to get attention. Just peek in on YouTube and you'll look at all kinds of people clamoring for fame. And they'll do anything for it, too. What's the big deal about having so many people watching you do idiotic things, especially when it's not your job? Are we all so hungry for celebrityhood? What is it about fame, anyway, that is so attractive?
Call it the Paris Hilton effect, when someone becomes famous for being famous. I don't get it.
Can somebody explain?
