Font recogniser

Well recently I need to match a font to logo we were using on a webpage. I could have just used any old font and most people wouldn't have minded but me being the perfectionist I am - I want to try and get it RIGHT!

In comes the "whatthefont" website beta available at http://is.gd/78L49

You upload an image, or point to an image on the web then. After some OCR the site asks you confirm it's recognition of some fonts... and based on baselines, serifs etc. it will recommend some matching fonts.
