I have enjoyed looking at your threads. As a professional web developer I can offer you some good advice. If your goal is
SEO for your book and website, I would answerall questions that are posted. That will keep your threads active longer. The longera thread is active the longer you have high quality links pointing in to your website, thus better traction. If you can, post page links from your websiteas part of your answer. Like this
