Maurice, one of my few and faithful readers, blogged about a cool site called "I Write Like". Just copy and paste some of your own immortal prose into a text box, hit Analyze, and see who you sound like.
I went back into my 2006 archives and dug up some paragraphs from the original version of Twilight Express for analysis. This is the opinion I received. I am guessing that's it's mainly because Joyce always wrote in third person, like I did.
(Of course, if it had told me I write like a writer I don't like, I'd be pissed off and not posting this here. But Joyce is one of my all-time favorites.)
