UnShorten wordpress plugin

As you can see from the front page, I put all my tweets on my wordpress blog with twitter-tools. One problem that I have with this is all the shortened links I use like su.pr. I want blog readers to see the full link like I do when I’m using Brizzly.
So I’ve written a plugin to do it for me as I can’t find anything else out there. It uses http://therealurl.appspot.com/ to shorten the url
So here it is: UnShorten plugin.
