I was talking to 3traditions about this last night, and we were puzzling over what methods the program used to figure out what writing the person's was similar to. We ruled out content, because there's no way the computer could figure that out, we assumed.
However, I tried another story besides the one I put in, which happened to include shota. And it gave me Vladimir Nabokov. That's that creepy. |D;;;
I really keep meaning to make a real post. Hopefully I'll get the chance to do that today.
