I recently discovered a cool site called I Write Like, which analyzes your writing and determines who your write like. Facebook has a similar application called, What Kind of Writer are You?
Paste a few paragraphs of your writing from your blog, a novel, or website into I Write Like, click "analyze" and instantly it says you write like Stephen King or Ernest Hemingway or Cory Doctorow.
I usually don't put much faith in the accuracy of such gimmicky sites, but I put in two different passages from my novel, Dark End of the Spectrum, and both times it said I write like Cory Doctorow. Strangely, I never read anything by Cory Doctorow.
The Associated Press reported that the site was created by Dmitry Chestnykh, a 27-year-old Russian, who modeled the site after software for e-mail spam filters and uploaded works by about 50 authors. He never expected the sudden success and plans to improve the site's accuracy by including more books.
In any event, I wouldn't contact a literary agent or publisher and tell them you write like the author from I Write Like.
