Another difference between delegates and observers is that delegates
sometimes have the power of veto over some operation (e.g., -
applicationShouldTerminate: and -textShouldEndEditing:), whereas
observers of notifications are merely notified.

Sometimes wonder if we're going to run out of words to describe

because everything is overloaded with some technical meaning.
Still ... my point is the same. I think this is a semantics argument
waiting to happen ( :-) ) but there is no 'observing' going on, per
se. It's quite literally delegation in its purest sense, which is
distinctly different.
