Here is a little weekend fun for you:
My boss pointed me to this website called I Write Like. You enter in a few paragraphs of your writing and the software compares your writing to forty well known writers to see which one you write like. The algorithm that runs the software makes the analysis based on sentence structure, word choice, and other factors. Once completed, you get a badge that you can place on your website, facebook, or blog so everyone will know who you write like.
By the way, I write like Stephen King.
