The US date format isn't unintuitive if you're fluent in colloquial American english, because that's how we speak dates aloud. You're more likely to hear "March 12, 2010" than "12 March, 2010" in casual conversation.
That said, I try to stick to 12 Mar 2010 (abbreviated textual month) on the intertubes in deference to the fact that the rest of the world formats dates differently, and I find that to be a nice unambiguous middle-ground.
