Obama is going to have a poet at his inauguration. Her name is Elizabeth Alexander and she was recently asked what poetry added to the inaugural. Here is her answer, but don't ask me to explain what the hell she said:
"Poetry, because it is language distilled and because it is also such intensely precise language, provides us with a moment of respite and meditation, moments where we have to stop and listen very carefully to every word. We aren't listening for a message but rather listening for we don't know what exactly, but we're allowing ourselves to be stirred in some kind of way."
