Chuck Palahniuk, Isaac Azimov (I think the word robot triggered that one) and Arthur Conan Doyle.

Yes, same here. I tried a bunch of different texts and got, in addition to Lovecraft, David Foster Wallace, James Joyce, Kurt Vonnegut, Margaret Mitchell, Arthur Clarke, Leo Tolstoy (for a spoof combined review on Anna Karenina and Astrid Lindgren's Pippi Longstocking), Mark Twain (for a spoof combined review on Huck Finn and To Kill a Mockingbird), and Jane Austen (for a review on Mansfield Park).

Oh, and Hart Crane apparently writes like James Fenimore Cooper.

At least Oscar Wilde and Jane Austen write like themselves, though ...

I keep getting authors I don't read, don't intend to read, or don't like!

I got David Foster Wallace for my last discussion post on Digital Horror. I'm not even sure how I feel about that, honestly.

That was interesting. I used 3 different writing samples and 2 of them came back saying I write like James Joyce and 1 of them said I write like H.P. Lovecroft. I haven't read either of these authors so who knows how accurate that is...but still interesting.
