"Test" Tube for YouTube

This seems like a fun idea.  YouTube is opening up the door to their "beta" features so people can play with them and give feedback.  It's an area they're calling TestTube, and while they continue to develop stuff, you get to try it out.  Nice creative use of people power.  Not unlike beta versions of any software or system, but an interesting idea to incorporate it in a web site's growth structure.
