One issue there is that I know I personally decline to mod people if they already have a large positive or negative balance on a single post. (There are some posts which I think should sit at 0 rather than -30, or even -5, for example.) If I have to mod someone to see what others mods were then I will be much more likely to unintentionally karma-bomb someone when I really just want to see what other hackers here thought about their post.
