A techie reader tells me that Amazon rankings are calculated from viewing

hits on a particular book’s pages, not from actual orders. Oh, well. Seems

funny to call them “sales rankings” then. Still, there must be some

correlation. My publisher is impressed, anyway. Publishers track

Amazon.com rankings with rapt attention. And the signing offer stands, of

course. And I am still blushingly grateful for the interest. (It’s Prime Obsession, here, by the way.)
