Regarding the classic view, isn't there a bit of bias there? since people mostly only look at the front page, then the stories they vote up are chosen from ones already on the front page. So comparing what the front page would look like if only votes from old accounts counted doesn't say much since in all likelihood you'd see the same stories. Maybe a better metric would be to track only the first few votes that stories get to see if the same ones would make it to the front page?
