I like the 2010 Grace Hopper Celebration poster because it is recognizably an illustration of Midtown Atlanta, and, moreover, because it actually has Grace Hopper on it. Also because it doesn't scream "Breasts! Tiny waists! Vague, ineffectual hand gestures!" like the 2008 one did.
Of course, for a few years now they've been putting the white chick in the middle and making her the tallest. Okay, so, speaking as the white chick, I usually am the tallest. But that doesn't mean I should always get to type.
