This is an interesting question. It would certainly prevent a bunch of bad behavior and force people to be more intentional in their voting. Here are I think the main reasons we /​ LW have talked about it but not implemented it:
a) Some people just read way more of the Forum than others. Should their votes have less weight because they must be spread over many comments?
b) I don’t want users to have to think about conserving their voting resources. If they like something, I want them to vote something and move on. Karma is fun, but the purpose of the site is the content.
