...which isn't exactly what I'd have thought, y'know, reading it. And having read Joyce. I also inputted the text of "A Perfect Creature" (forthcoming in Like a Vorpal Blade) and it told me I write like Chuck Palahniuk. And for "Kashrut" (in New Blood) I write like Margaret Atwood. And "The Path That Few Have Trod" (in Trail of Indiscretion #10) is "written like" David Foster Wallace. I expect all the others will come up with different responses as well.
Which I suppose might possibly mean that I write like me.
On the other hand, I wouldn't be too terribly surprised to feed it a chapter of Vonnegut's Breakfast of Champions and be told that it was written like Hemingway.
