Most people seem to angle them up, which ends up with almost the same body position. I don't have them angled down so much that the side position is unusable as an alternative hand placement. The main issue with doing this is the cable position on your brakes and shifters. Some simply foul the headstem when the bars are angled down and the levers are in a rational position.
