What's this? The New York Times bestseller list "is not a completely accurate barometer of what the reading public is buying," public editor Clark Hoyt informed us last week. This, even in spite of recent adjustments to the top-secret formula, devised in order to prevent publishers from "gaming the system" that determines the list's rankings: Appalling! Well, not really.

Unless those authors have bestseller bonuses in their contracts, in which case: The list is extremely meaningful! And so while the list does not mean everything, it must mean something. For example, the #1 spot on this week's Hardcover Fiction list is occupied by a John Grisham book called "Playing For Pizza." What's that about?
