Heh, you say that as if I didn't know! ;)
I'm sure you've noticed that in computer UIs, all the "3D" effects are based on the sun being at the top. Same with geography -- it's easier for me to visualize the terrain if the sun is at the top. That means South-up in the northern hemisphere, and North-up in the southern hemisphere.
