Karma, like any measurement of an individual's value is imperfect. I'd say that it's not closely tied to a user's contributions to the site. And seriously, abstracting something like it represents into one number is problematic except with gross comparisons. A well made comment in a discussion may get 4 - 6 points of karma. A link to tech crunch article or blog post you had nothing to do with may get you 200+ points. People upvote people they like, regardless of the value of the particular comment. This means famous individuals tend to have more karma per post count. I'd personally love more details on karma. especially karma from comments, as separated from karma from posts.
