Become an Amazon Author

I just learned a few minutes ago that anyone can become a published (and paid!) author on Amazon. All you need to do is have an Amazon account and go to the Kindle Direct Publishing section of their web site. I haven't actually tried to use the title-adding wizard yet, but it looks like all you need is a manuscript and some information on yourself. The home page claims you can get royalties of 70% for e-books and 80% for printed books. This might be just what I need to get motivated to actually collect my knowledge into something usable... and profitable!
