This is a fun site, where you can post a few paragraphs of your own writing – blog post etc and it analyses who you write like. http://iwl.me/
I did it twice with two different posts and got two different authors. Not sure how they analyse it; but thought it was interesting and I’m going to look into the two authors now.
David Foster Wallace (February 21, 1962 – September 12, 2008) was an American author of novels, essays, and short stories, and a professor at Pomona College in Claremont, California. He was widely known for his 1996 novel Infinite Jest, which Time included in its All-Time 100 Greatest Novels list (covering the period 1923–2006).
Cory Doctorow (pronounced /ˈkɒri ˈdɒktəroʊ/; born July 17, 1971) is a Canadian blogger, journalist, and science fiction author who serves as co-editor of the blog Boing Boing. He is an activist in favour of liberalising copyright laws and a proponent of the Creative Commons organisation, using some of their licences for his books. Some common themes of his work include digital rights management, file sharing, and post-scarcity economics.
