The Nadir or Purest Form of the Blog-to-Book Deal?

Here's an interesting variation on the blog-to-book deal: the webcomic Garfield Minus Garfield, which simply removes the cat from all the Garfield comic strips, will be a book—published by Ballantine, the publisher of the regular Garfield books. ("Who would have guessed that when you remove Garfield from the Garfield comic strips, the result is an even better comic about schizophrenia, bipolar disorder, and the empty desperation of modern life?") It will come out in conjunction with the official 30th anniversary of the Garfield book. Creator Jim Davis says he approves!
