I submitted several writing samples from my blog to the statistical analysis tool I Write Like. Apparently, I write like H. P. Lovecraft most of the time, of whose writings I am a fan.* The second writer who came up consistently was Cory Doctorow, and I have read and enjoyed many of his short stories as well.
Both are writers of science fiction short stories, and their writings are available either in the public domain or under the Creative Commons license, which means you can find their short stories for free on the Internet. If you are lucky enough to have an iPhone, iPod Touch, or iPad, you can install the free app Stanza and find these and other free works under the “Feedbooks – Free Content” catalogue.
* I am not a fan of his pathological racism, however.
