Nice, but the link from your name misdirects, and the image there is also labeled as http://twitranking.me/twitter.com/images/getrank.png, so it doesn't seem to work properly (because of the extra twitter.com in there). It also doesn't degrade 100% gracefully when given malformed input (like <'>, etc)

But cool! I tried it out and it's a handy tool. Add some stats to show off.
