Course on how to write Technology Reviews?

You can earn money from teaching anything these days. For US$65, you can learn how to write a tech review here. Is it really necessary? I didn't need such a course when I wrote for CNetAsia and other publications. I bet the instructor didn't need one when he started out either. Anyway, Gizmondo has a list of humourous, and perhaps more practical, Insider's Tips on each of the items that the course is suppose to teach you.
