Indifferent Button

Everyone is always talking about how Facebook needs to have a
"Dislike" button.  While I agree that would be neat, I think there is another button that is needed much more.  I am referring, of course, to the "Indifferent" button.  It could also be called the "Who Cares?" button, the "Why Did You Waste Time Writing This?" button, or the "Who The Hell Gives a $#!+?" button.
