Yeah, the way they implemented it was really flawed. Since it's inside the profile no one really bothers to go in and click up an X amount of times. The way it should have been done, is put a little + or - icon somewhere beneath the avatar or post count of the user, and you give them 1 point only. The more points people give them the more Karma they build up. There would have to be a system on how your points have effect, such as you couldn't plus Karma the same person within a month or something, perhaps if you have not been given Karma lately you cannot pass it on and influence others'... just thoughts.
