Everything is different.
If you don't believe this, let me redirect your attention to Exhibit A, Queen Rania of Jordan's YouTube award acceptance video. If you don't remember it or missed it, here it is.
Well? A couple of things pop to mind.
1. This woman is a queen. One of the only real queens left on the planet. Look at her presentation of herself here.
2. She is assuming that everyone watching recognizes the format. Letterman as a cultural universal. The mind boggles.
3. She also assumes a good knowledge of YouTube. OK thinking of her original audience, but as we know, these things move around.
3. Unable to appear in person, she makes a video. If you think YouTube is a natural form of expression solely for pimply 14 year-olds who never leave their basements, then this video is a sharp answer for you.
I hadn't intended to use this in class when I first saw it, but watching it again, I think I will use it. Tomorrow.
