Online Porter Stemmer

I was looking for an online version of the Porter Stemming algorithm. I couldn't find one, and then realized that I am the person most recently credited with the official JS version here: http://tartarus.org/~martin/PorterStemmer/

So I guess then, it's my responsibility to make a demo: http://qaa.ath.cx/porter_js_demo.html

There it is.
