How YouTube is testing their new Beta

Today I discovered the new beta version of YouTube. I am not sure what the big difference is, and I am not sure if it`s only the design they are testing or not. But what I am more focused on is how they get people to test it and how they are doing the switch. [singlepic=14,400,213] When you are watching a video at YouTube (Muse playing Starlight), just to the right of the video, you can see the highlighted text "Try out the NEW (beta) version of this page!" I think that this is a great way to test it, it`s very similar to how PayPal was testing their new design. By doing it this way, everybody (who sees this) can watch the new design and compare it to the old. And maybe somewhere they can submit their thoughts and ideas about the new design as well? The reason I really like it, is that it doesn`t take your focus away from what you are really looking for (the videos). But at the same time, I don`t think that most people will have a problem seeing the highlighted text. The feedback option was a lot easier at PayPal, but I am not sure if YouTube are looking for feedback or not. And as I said, I am not sure what`s new with the new beta.
