Are you saying that the sleep data is more personal than calling 911? I have to question that, because you could call 911 for all sorts of private situations that you wouldn't want publicly known. So no, it's not really different.

Especially in this case. Saying something like, "I couldn't go back to sleep after that earthquake woke me up" is the kind of thing many people would share on twitter, facebook, or around the water cooler with coworkers.
