OK, this is really cool. Via John Fea's The Way of Improvement Leads Home blog, a website called I Write Like. You plug in a piece of your writing and it compares your style to a famous writer's.
I plugged in 3 different things from the comments section, plus one of my formal essays, and it came back the same all four times---Edgar Allan Poe.
Funny thing is, I've never read a lot of Poe, but I remember in about the 6th Grade, they taught us "Poe's Law of Single Effect," that the meaning and sound of each word should propel the story. That sounded like an ace way to write, and I've kept it in mind all these years.
Now if it turns out that half of us write like Edgar Allan Poe, it won't be all that cool. But for now, this is like one of the coolest things in the history of the world.
