I think videos of David Pogue in New York Times are good examples of the well-done video cast.

Please click the next link to see one of his video cast.

He is using various video sources not to bore his viewers.

However, the most important thing that I think we should notice in his videos is that he actually throws the authority away.

It is certain that he is one of the authorities in the tech world.

However, in his videos, you can not see any signs of authority such as formal speaking (at least he is not reading a script) or wearing a formal suit. You will see that he does not hesitate to make himself laughable in many of his videos.

He is also constantly taking advantage of lay people's voices. You can see that a lot of lay people are appearing in his videos. Even his son appears in his video (http://video.on.nytimes.com/?fr_story=6ffd976ed367bacae4171dd4999d36431c84b0f5) It makes him look like a guy in your neighborhood who want to tell us a very interesting story.

Ironically, by discarding his authority (or pretending to discard his authority), he is gaining an authority, which is actually given by viewers. Please search for "David Pogue" in YouTube.com and you will see a lot of copies of his videos and numerous enthusiastic comments on his videos.

About 4 decades ago, Roland Barthes anticipated "Death of the Author." He actually anticipated the power-shift from the author to the readers via the text. Thanks to the hypertextuallity of the Internet, we are living in the world where the authors don't have authority anymore. However, we are also observing that there are people who are enjoying the authority given by the readers and viewers. The key questions here may be "Are you really ready for interacting with lay people?" and "Are you ready to give up your authority?"

Instead of my ending comments, let me introduce David pogue's blog.
