I notice that the book provides links to the original articles, and in the introduction Rob encourages people to comment at those links. I'm going to now agree with those who promoted just putting in a link to the original article. As of this comment, the votes on this were 7-6 in favor of posting the whole article. But I'm switching my vote (don't know how to do this on the original poll), which makes it 7-6 in favor of just posting a link.
