If you go to any video on Youtube right now, you'll see there are 0 dislikes. The bar is 100% green. A while ago they switched dislikes on the rating bar from bright red to a subtle gray, making all the ratings look a lot more positive. Are they just having technical difficulties right now, or could they be easing into an only positive feedback system?
Since no other commenter has mentioned it, I figure I should mention that I'm also not seeing any dislikes.<p>But since other commenters do see dislikes, I think it's more likely technical difficulties than an attempt to phase into an only-likes system.
in my case i still have dislikes in my videos, but i'm subscribed to videos with very low viewcounts anyways (a week-old video will only get 200-800 views in most of the videos in my subs)
