Video sites for learning to use technology

Everyone knows YouTube, don't they?

But there are other great video sites, too, which are particularly useful for learning how to use technology:

• www.teachers.tv
• www.teachertube.com
• www.videojug.com

You can read about how to do something in a manual, or find a text-based tutorial online somewhere, but sometimes actually seeing how something is done is so much more helpful!
