It was taken away (I think a few months ago) because some users were using it as retribution. The order of things was useful or inciteful comments should rise to the top and everything will drift down. Now if they integrate a threshold filter ala Slashdot that would be useful. But yeah, the lack of the down arrow doesn't really do anything except to the root comments.
