Stumble Upon

If you love internet videos, but don’t know where to start (or what you feel like watching) try StumbleUpon. You just pick some categories of interest and hit the Stumble button and the videos come from all the major internet video providers. Select the Thumb-Up button if you like it or the Thumbs-Down if you don’t. The site will show you videos based on your choices. It’s like a choose-your-own adventure for videos. This makes it very addictive and in a lot of ways, better than regular television.

You can always change categories to get a wider sampling of videos and it's best if you sign up so it remembers your choices. Another cool feature is that you can easily look back at all the videos from each category (likes, dislikes, non-votes).
