The key takeaway from the article (as far as I'm concerned) is this:

> "So if you write a book it should not be because you want to make a lot of money from it but because you have an idea that you want to present to the world. And as an author, you owe it to yourself to get your idea in front of as many people as possible. By putting the book in your web site, you make it available to many people who would not otherwise have access to it: poor people, high school students, people in developing countries, and so on."

... Which is why I give all my books away for free[1][2], and have been doing so for over 10 years.
