If I read an article that's an excerpt from a current or upcoming book, I decide whether or not to buy the book based on how much I enjoyed the article.  (Gee, how's that for a breathtakingly radical, brilliant idea?)  Based on the articles, I'll be getting both Mr. Weaver's book and Mr. Mank's tome just as soon as they're released.  Besides, even sight unseen, you CAN'T go wrong if the byline says Tom Weaver or Gregory William Mank!
