What is fun to do on the internet if you are board

www.stumbleupon.com is my favorite time waster on the internet. You fill out a mini profile about what you like, click stumble, and it will take you to a variety of sites that the website thinks you will like. I have spent literally hours at a time stumbling, and it rarely fails, but when it does send you somewhere you don't like, you can just stumble again.
