@pg, i think the average is a bad way of doing it. it discourages people from commenting on low-traffic, or old threads. the game becomes that of other threaded comment systems where you get more up votes on heavily traffic-ed threads. it should push the long tail of comments further out, and have fewer threads with high traffic. someone trying to game the system might look for threads with say 10-15 points and then make a comment, hoping they get above the average. it's like investing in DOW companies during an economic upswing. your karma actually should not be purely based on uptick, but should represent some amount of risk you took, and then measure that against how well the community responded to it. so commenting on old or low-traffic threads could still be of value.
