The only problem I see with this is, people not using it seriously, or even correctly for that matter. Most of the people on here would just down vote others because it'd be "funny" or for simply no reason.

Its likely that people here will race to get the worst karma rep vs a good karma rep

That too. People will think it's cool because they have -87 karma and make fun of the guy with +112. Who knows.

Personally, I love the idea of the karma system on forums, but this forum wouldn't handle it responsibly imo. Unless there was a way so that only moderators and administrators could do it? Not only to help keep it controlled, but it would be more reliable? I don't know, throwing ideas.
