Stumbleupon is a great site for when you’re ready for some serious interneting, but aren’t quite sure what you’re after.
StumbleuponVideo expands on that idea, providing you with random videos that you’re sure to love.
But where it gets really clever is how it allows you to thumb up videos you particularly like. StumbleVideo then ‘learns’ the kind of videos you like the best and supplies you with more of them in the future.
Another great thing about Stumble videos is the great, no-frills video interface. You don’t get comments, etc, just the bare bones and Stumble controls all on the plain black background.
