I write like
Stephen King
I Write Like by Mémoires,
Mac journal software.
Analyze your writing! I used 44 longer (non-meme, non-survey) samples from my LJ, including 4 short fanfics.
15 came back as Stephen King, 8 as Kurt Vonnegut, 8 as Chuck Palahniuk, 4 as Dan Brown (ugh), 2 as Bram Stoker, and tied for 6th place with 1 a piece were Margaret Atwood, Raymond Chandler, James Fenimore Cooper, Harry Harrison, Edgar Allan Poe, William Shakespeare, and PG Wodehouse.
Although I wasn't paying attention the first time it read an entry as Bram Stoker, I suspect that the second time was only because I actually mentioned Stoker in the post and was talking about vampires.
I leave it to you, gentle readers, to say whether any of this is accurate, as I have only read 4 of these authors, and King is not one of them. (I'll let you guess which 4)
