How should the date be formatted (dd-mm-yyyy vs yyyy-mm-dd, etc)?

I like mm/dd/yyyy because that's how so many people (here) say it verbally (it's July 13th, 2012 - 07/13/2012). dd/mm/yyyy makes sense because it goes from smallest, to bigger, to biggest. But whatever. It's not really something I care about.
