Teaching Us is a video blog run by a woman who is passionate about education. It isn't specifically about CS, but it is pretty interesting. I like that she's trying to highlight what is *right* about education rather than decrying about what is *wrong* in education.
The first video inspired me to want to try video blogging myself. (I did eventually come to my senses and realize that I'm a word person, not an image/video person, I don't have the technical know-how, and most importantly, I don't have the time to get the technical know-how, though I'm sure I could figure it out.)
She ran into some technical problems that delayed the second video, but the wait was worth it.
