Pinched this link from a TV thread, pretty cool site....
I Write Like
It uses some kind of stats analysis to compare your writing style with someone famous. Probably just useless novelty but a smart website, as rather than linking to the author it tells you you write like, it links to an amazon page selling their books.
Apparently I write like Cory Doctorow, some lefty I never heard of. Didn't even think I had a style, thought I'd be compared to some 8 year old story writer.
Who does your writing style emulate?
