I suspect that "Rework" suffers from the same fate that many hot business books suffer from: a lot of people buy it more to display it on their shelves than to actually read it. They imagine they gain some degree of intellectual credibility every time someone walks into their offices and sees it on the desk, or above the computer in a stack of brightly colored and catchily titled books by Kawasaki, Godin, Gladwell, et al.

I've actually read "Rework," and I quite enjoyed it. So I am not speaking ill of its content or its value whatsoever. But we should be honest -- and, sadly, uncharitable -- about what percentage of books sold we believe are actually being read. Especially in this genre.
