Just in case you missed it, here is the clip of Anna Wintour on Letterman last night. What interested me most about this interview was her overall demeanor. While she probably isn't the most polite person ever, I like how she says what she means and means exactly what she says. Unapologetically.
They cut the part where she walks onto the stage complete with her dark sunglasses. However, what makes this a such a great clip is how human she comes across. You see the side that isn't portrayed in the papers. You see beyond that.
Or maybe I'm just romanticizing the clip. Why not take a look.
