I have been getting the same experience. I actually got my first three digit karma comment soon after pg made the change. And I have been here for more then 2 years now. I think when there are visible comment scores people do not vote based on whether they like a comment or not, they vote based on whether a certain comment deserves the current karma or not. Thus, they are likely to downvote highly voted comments not because they disagree but because they think "this bastard does not deserve THIS much karma".
