StumbleUpon.com is a crime. Sites like that just shouldn't be allowed on the web. Its really just a site that you plug in your interests and it sends you to a random page that it thinks you would like. Before you know it you have been caught up in a hopeless cycle of finding cool sites. Its definitely worth getting the toolbar, but if you do, then don't expect to get any work done. You can spend hours just clicking the Stumble button.
