The faq claims that at 750 rep, one can see the total up and down votes. I don't see that when I look at questions. Where is this information displayed?
You have to click on the total number of votes, whereupon it magically splits into a green number above a red number. I'm guessing that the green is good and the red is rubbish (though it might be green for garbage and red for rather spiffing), but this particular question has garnered no votes as yet so I just see two zeros.
