It might be that people see this headline and are interested in returning later to skim the book list and all of the other lists linked here in the comments. Upvoting Bill's book list might not mean they like his list, think it belongs at the top of HN, or that they even read the blog post. The top-of-front-page ranking could just be the result of a large number of readers upvoting in order to have the discussion show up in their "saved stories". edit: A "save story" button that is independent of the voting/ranking mechanism might actually change the front page significantly.
