so i guess the rep controls for comments are:
Perhaps the two-up arrow does three things at once (not sure about this though, we may just want to never promote comments):
Next to the agree / disagree pseudo-hyperlinks, we show the percentage agreement, moved towards 50% by 95%-confidence (that is, take the upper or lower bound of the 95% confidence inverval, whichever is closer to 50%, or 50% if it's within this interval). Perhaps if you mouseover or something you can get the absolute agree/disagree numbers.
When you click on the questionmark, a box pops up where you can predict that either the comment rank will go up, or will go down, or will stay about the same.
