I can't stand it! It just seems so much less accessible. I really do wish they'd change it back, but I doubt that's going to happen.
Oh well, YouTube was gradually going down the drain anyways, now that big corporations are taking notice of it and putting ads on the videos. Ads! One of the main reasons I used the site was to avoid ads! Now, with that and the implementation of a much worse interface, I'm hoping someone's working hard on the spiritual successor for YouTube, so we can all migrate there just like everyone jumped so quickly from Myspace to Facebook.
