Apparently I write like Cory Doctorow. I am fine with that. But you could take any non-fiction prose and have one answer. Need more evidence that they also looked at Michael Lewis, Malcom Gladwell, etc.
Interestingly I got Doctorow too for (technical) blog posts. For fiction stories it gave me: James Joyce, Arthur Clarke, and Kurt Vonnegut.
My science fiction stories got Asimov and Clarke. My fantasy stories got Tolkien. It is kind of suspicious.
