Reduced rewards for voting after a post is already popular is not "punishing" those later voters, it is just recognizing reality that those votes are in a sense less valuable. I say in a sense because votes can be interpreted on different scales. If something goes from 0-100 votes, it is less valuable for it to get one more vote, but still probably extremely valuable for it to gets to a million votes. So something that discourages or even fails to reward votes 101-999999 is not necessarily the desired incentive structure.
@smooth's proposal solves that effect gently...
