>we get about five times as much from a hardcover as a mass-market paperback

Want to support writers? Instead of buying four paperbacks, buy one of them in hardcover and pirate the other three.

Good advice for anyone. Thank you, sir.

I'll still buy paperbacks, because I can't pirate books...reading a book on a computer just isn't the same as reading it on paper.
