I can see why the change is for the better: my vote (-1, 0, 1) should not be skewed/altered based on past events (others voting). Also, an "appropriate" total vote count is not something that an individual should be determining; it should be a collective thought. The only thing an individual should decide on is whether to award the comment a -1/0/1 purely based on the comment, nothing more. This change removes everything else (or so we assume: but considering the fact that the position on the page is still modified, it's not perfect, but it's close enough in my book).
