I see a lot of people with the facebook status "sleeping".

I doubt that.

Although, I'd be interested to see if someone were actually asleep while simultaneously on facebook. Beyond being impressed by their ability to sleeptype, I wonder what implications you could draw from someone's subconscious being able to work with facebook's interface. I don't think they're too many people out there like that anymore- I've observed people becoming less attached/OCD about facebook and using it more for specific reasons (ie sending a message or starting a group to promote an activity or just straight up stalking. It's interesting then that Gmail seems to be moving in the opposite direction- as facebook becomes more like Gmail, Gmail becomes more like facebook with Buzz and the odd duck that is Wave) as opposed to just bouncing around from page to page.

There are exceptions of course, namely the people who play Farmville. People like Missy Smith. I swear, Miss Smith, if you send me one more invite with a free chicken coop attached or start one more pillow war or whatnot with me, I will tear everything you love in half. Love your farmville accout? Your cat? Your mom? In half, Missy. In half.
