Oxford Dictionaries online are running a fun little app that you can use to find out how 'Shakespearean' your writing is.
Simply copy a paragraph of your writing, paste it into the box and hit the button at the bottom. It calculates how much like the Bard you are by comparing the number of words you use that he also used. I got 85%, which is pretty good going in a small paragraph about a swimming lesson!
Mind you, the calculation was so incredibly fast (really, almost instantaneous) that the cynical part of me wonders if it just plucks a number out of the air at random.
It's still a bit of fun, though.
