If you want to pick up $500 fast, just impress Lisa Haneberg with your artistic skillz. She's got a Web 1.0 thing going on with the current cover of her book High Impact Middle Management (a book I love, by the way), and she want to bring it up to at least Web 2.0.

By the way, I always thought this book should be called "Badass Middle Management" because it has some fantastic advice for anyone who wants to be more effective as a manager, particularly those of us "in the middle" of an organization. Another reason to love this book is that it takes you through an abbreviated version of one of my favorite topics: Goldratt's Theory of Constraints.
