StumbleUpon - Welcome to StumbleUpon StumbleUpon is essentially a more randomized version of Digg. You chose a bunch of topics you're interested in (for instance I have Atheism and Agnosticism, Liberal Politics, Humor, and Rave Culture), and hit the Stumble button on your toolbar. It takes you to a page of one of those topics that a member of the community has recommend- more recommendations means it's more likely to appear. It's addictive and you can find some awesome websites. I just added GeneralForum as a favorite, if a bunch more people join and favorite this page we might get some more traffic this way.
