I pasted in chapter 1 of "Harvey the Hawk". It told me I write like Stephenie Meyer, author of the "Twilight" series. Ew!
I pasted in chapter 2 and it told me I write like David Foster Wallace, whom I've never heard of. Wondering whether it uses an algorithm or is just random, I ran chapter 1 through again. It said Stephenie Meyer again, so I guess it's not random.
Then I tried an LJ post. I fed it my Cincinnati & Blue Ash post, and it told me David Foster Wallace again.
I gave it More thoughts about Toy Story 3; David Foster Wallace again.
Experimentally, I fed it the text of my latest diary update... it told me I write like Arthur C. Clarke. I'm baffled.
