Replying to Comment Score

With the new(ish) addition of the comment up/downvoting I figured that an overall score would be a nice addition. You could click on someone's profile and would be able to see their total post/comment score. It would be a better look at what kind of poster people are instead of the obscure numbers in the karma. Not saying that this should replace NS karma at all because that is a culmination of many different things and has had a long history on NS. Also would encourage people to post more positive comments if they can try to build their score up. What do you guys think?
