The folks at Lulu kidnapped some scientists and forced them to quit working on actual things and figure out the probability of popularity of books based on their titles. Plug in your book title and see if you have a high chance of scoring a bestseller (unfortunately you can't plug in the entire text of your book and have that scored.) NB: A Million Little Pieces only has a 63.7% chance of being a bestseller. I guess there's no way to plug in the Oprah factor.
