I just saw a couple of my books on what appears to be a forum for file sharing (I'd have to sign up to see the actual link, and I'm not going to bother). Some enterprising soul kindly uploaded the books there, and four people have thanked them for it already. I know piracy happens, and I generally don't get real stressed about it, but come on, is 99 cents really that much to pay for a book you want? Really?
Oh, well, guys, enjoy the books. Maybe you'll consider paying me 99 cents for the next one you want to read *shrugs*.
