Is the average number of comment upvotes per day the same? Would that prove that people don't care about how many upvotes a comment has when they vote? Or how about the distribution of upvotes over comments under one post -- are upvotes more uniformly distributed? Do the comments on the bestcomments list have greater or fewer upvotes on an average?
