There is now an online amusement for writers and non-writers alike called I WRITE LIKE... where one submits a sample of one's writing and it is immediately assessed to be "like" whatever writer's writing it decides your sample resembles.
My first submission revealed that I write like Stephen King -- which I don't mind.
My second submission revealed that I write like Dan Brown -- which I do.
Yes, I know the man has made millions. I'd like to have his checks -- it would help my assorted loved ones to no end if I had a cash flow of that magnitude -- but I do NOT want to write like him. I can say that I admire his storytelling, i.e., the unusual premise of his Da Vinci book. But his way with words? Not so much.
