Classroom 2.0 post

Obviously I'm spending time today at Classroom 2.0. I posted this question that you are free to answer either here or there! 

We have started using You Tube and Teacher Tube in our K-12 classrooms for a variety of activities including (but not limited to) political science commercials, commercial spoofs and so on. We will be presenting at a tech conference at the end of April and am looking for other ways that you are using. Credit will definitely be given!
Here are links to our district HAL You Tube and Teacher Tube pages. Thanks for sharing!
