That's the problem with gamifying something. Eventually you'll get people who are only there for karma. The other day I found an incorrect answer that was chosen, but directly below it was the correct answer. The kicker? The OP commented on the correct answer saying that his was correct but the guy other guy had less karma than him and "needed it". WTF. These days, you really have to take Stack Overflow answers with a grain of salt.
