Have you played with the site that analyses your writing?
Twitter's Guy Kawaski at Alltop provided the link.
It is called I Write Like.
This was the quickest piece of analysis I have ever done. It was a lot of fun too.
"Want to know who you write like? You can go to I Write Like, paste in a sample of your writing, and find out. The site has analyzed approximately 1.5 million samples of text already. The creator of the site, Dmitry Chestnykh, explains how it works." etc
