Video Blogs

I have been watching Rocketboom lately. Is anyone else watching any video blogs? How many good video blogs are there? What should I be watching? I am looking for the feedback.

Sometimes I wonder about video blogs. Either they are the wave of the future or they are just a fad. I can see them being either. Not everyone has something to say. There is too much content out there. Will there be a way to find good content?
