I had heard about Hulu but never went to the site. What a wonderful collections of videos! I also liked Blinkx, especially U-Zoo The Cutest Pets Ever. Because these sites are free and easy to embed in presentations, I think I will be visiting them regularly and use them in my Flipcharts and podcast. I have used PBS and National Geographic videos before and they were extremely effective. Some of the short clips could be used for discussions or story starters.
