YouTube

While I am thinking about it, I just want to record some ways of using YouTube.
I like Tubechop (http://www.tubechop.com/)  because it removes all the other stuff around the video and you can find the embed code easily to include in your blog or wherever.
Kickyoutube (http://www.kickyoutube.com/)  - allows you to save the video to your computer. I clicked on MP4HD and it seemed to work.
Snagtube (http://www.snagtube.com/) - lets you keep the video. Haven't tried it but it gives you the instructions.
Be aware - I am not sure about copyright implications with these sites.
