The upvoting/downvoting mechanism should be sufficient unless you have a scenario where people are upvoting titles without reading the page.

Note to author: perhaps more enticing would be to have 4 examples, the first being a free preview of the book and rest would require payment. Then people could evaluate your tutorial style.
