I don't know how many people have dropped conductive material, against a wall, and try to catch it, but I imagine there are far more people unplugging things. Duplexes can be installed in any direction, there is no set upside/downside.

Here in NS the ground pin is down in residential buildings and up in commercial buildings. I'm not sure if it's code or not but it seems to be the way electricians are taught here. ( I've asked a few different electricians over the years.)
