I think a great way to spread the word about CB is students. I'm currently taking 1 class distant education. So far, in the 2nd week, I've found a way to bring Chuck into the online discussion, post information from his website, and link directly to it.
Just background for anyone interested, I had posted a rebuttle to an article published here locally that high gas prices were going to hurt the Republicans in November. I attempted to explain why it would also hurt Democrats. I had someone who accused me of attacking Obama (even though I didn't even mention him). I informed the class that I wasn't planning on voting for either Obama or McCain and then gave a couple of sentences on CB.
