So apparently YouTube is no longer on iOS 6.
If this isn't some sort of glitch — good.
I don't know about you but I never used the app — it performed poorly ever since iOS 4. I would usually have to copy and paste link into Mobile Safari and prepend an m to the URL in order to have the video play correctly. Plus, I was never the type of person to launch the app and browse — I always had a link from search results or other sources that linked to videos.
