I'll use the sun or a compass to pitch my tent so it'll catch the first rays of the morning... tent gets dry and you get an early start.
I've stopped carrying a compass now that my iPhone has one
I am never so lucky that I can find a flat unlumpy area that is so big that I can pitch my tent oriented in any direction, I usually am pitching my tent to take advantage of the tiny flattest and smoothest area to sleep on that will not fill up with water during a downpour.
