While I agree with the premise that voicemails that provide no additional information are not useful, the author is an elitist jerk. That being said, callers generally have no idea if you aren't answering because you're not near your phone, or because your phone is off/without reception/on a plane, in which case the call notification would never appear. Google Voice does a good job of solving this by includes notifications for missed calls, but everyone else has no way of knowing they missed a call.
