Has anyone created one of those quizzes (like "Find out what sort of farm animal you are!" and the person posts the result on their page with text like "I'm a donkey!", a picture of some unfortunate burro, and, the important part, a link back to your site)? If so was the added transfer of serving the images and the trouble of creating the quiz worth the traffic it brought? I did this once with mediocre results, and was wondering how other people fared.
