Patrick,
While I believe the plug should be oriented in the position so the ground is on the bottom of the receptacle, in certain cases they should be placed on the top, such as with metal cover plates, so if the plate falls off it will hit the grounding prong first without seriously electrocuting anyone.
I don't think there technically is an up side down to a receptacle, just a preference on the part of the installer. If you take notice, when you walk into commercial installations you will see that many of those installations are up side down, with the grounding prong at the top.
When you see them up side down in a home, that means the guy that installed them has also worked in commercial installations.

Ok, when then why do the cord manufacturers place the ground on the angled plugs on the bottom? You will notice that the cord would look pretty funny sticking up in the air.

If the ground is up, the cords with the 90 degree molded plugs on my refrigerator, microwave and washing machine would travel up the wall several inches until gravity took over. I think this would cause the plug to become at least partially unplugged. That can’t be good.

I know it looks like a 20 yr old cord but it is the only pic I have.
