Express yourself!  That's the tagline of the fastest growing website on the Internet.  YouTube, recently purchased by Google for 1.6 billion dollars, allows any user to upload a video and show it to the world.  YouTube embodies Web 2.0 featuring a slick interface, comments, ratings, and social networking.  One of the coolest features that YouTube offers is embedding videos inside of other pages, so you don't have to go to the site itself to show your friends that cool dance move you've perfected.
