I see they asked you about writing a book. I've been waiting for you to write the definitive book on SEO.
Have you thought about bypassing a publisher and just producing a PDF and selling it directly? Then the only cost you'd have would to pay for a good editor and the rest would be profit.
I'd gladly pay $50 to learn everything you know about SEO. I'd bet you could sell a couple thousand copies on HN alone. Would that be enough money for it to be worth your while?
