Meta: Why have a jump if there is no content after it? [Find out after THE JUMP]

It is officially OT season and I have been wondering about this for a while, why have a "READ MORE" button at the end of a post if there is nothing more to read?

Does anyone else still click the button anyways, you know, just in case?  And before most of you say, "never", I am sure Seth or Brian can generate the number of clicks the "READ MORE" button produces on the posts with no additional content.
