Was feeling very conflicted over the whole Free Documentation issue until I read Tim O'Reilly's views.
I write copyrighted, non-free books and articles on free software for a living. The paradox bothers me. On the other hand, I also contribute to free documentation. On the other hand, I spend a lot more time on the non-free documentation than I do on the free documentation. Still, I have a son to feed, and so far free documentation doesn't pay for the groceries. (Neither does the non-free stuff, for that matter).
I made a contact with an O'Reilly editor, who assured me that they are willing to publish under the Open Content license. That's a start--now all I need is a proposal. Grrr.
Will go study my C book. I always feel better after I've studied my C book.
