<p>I write many book reviews on amazon. CV may be a better online place to do it as it would be focussed.  Whenever I go to stat meetings it always astonishes me that people recognize my name because of my book reviews and comments on the ASA egroups rather than my own books and other publications.  I also have done many book reviews for journals including Significance and Technometrics.  I have an incentive there because they give me the book for free to review.  </p>

<p>On amazon there is a rating system that caan be used to vote on their customer reviews.  Our upvote/downvote serves a similar purpose on a grosser scale.</p>
