I like this video for two reasons:
1. As a kinesthetic learner (meaning I have to move to retain new information), I like the motion of
kinetic typography. I pay attention because I wonder what the shapes are going to look like in the end.
2. I am always interested in how language is changing and how it’s the teenage generation that pushes new words into acceptance. This essay on language by Stephen Fry discusses why it's not a bad thing.
For more about this kind of animation, search "kinetic typography" in YouTube. There are videos on all sorts of topics using it.
