I discussed this a bit with Turntrout, and one solution (that comes with its own problems) is some kind of karma-decay function that has you lose some fraction of your karma on a continuous basis. This would make the karma more similar to ranking systems in many online games, where the rate at which you can gain points determines your final stable ranking, instead of just the amount of time you play.
