These apps, albeit being really "cool", make me uneasy. I agree that it uses negative reinforcement to help you get your sleeping habits in shape, but I do not like the idea of an app punishing your laziness by making a mockery of you in front of your friends and the world. Is sleeping not supposed to be a private affair? Do we really want to notify the world of our sleeping habits?

Moreover, would you really like to see YOUR wall flooded with "Your friend, "XYZ" is a lazy-ass!" feeds as soon as you wake up?
