I'm excited to see what they do with this. It could be super cool. I also love that they got Neil deGrasse Tyson given his great work on the PBS programs Nova and Nova Science Now.
I think he is one of the better communicators of physics and astronomy to the general public. I like how he doesn't water stuff down in the name of simplicity like many do when the TV cameras turn on. He always chooses his words carefully and admits the limits of his analogies.
