Stumleupon

I love stumbleupon. It is a great way to waste some time if you are bored. I have probably spent hours at a time on here. You choose topics you are interested in and then you install a toolbar and you click the little stumble button and you are directed to sites that you would (maybe) like based on your preferences. I usually like what I find! It only takes a few minutes to set up! Do it! :)
