Well not really ... Its just gives you the advantage to give a + to the people that atleast post stuff that aint made out of 3 words and dont post just for the post counts , and am not sure why you should give + to an admin anyways :3

The best of reputation is that people that just post ''Nice updates'' or ''I like this topic'' without anything alse are short and boring , you can now dislike. So you can dislike those post whores ;P ( like the two above me)
