I'd like to add the one that bothers me most: 6 - listen to public talks, presentations and soundscapes while doing something else with my mobile device, or letting the screen sleep in my pocket. YouTube requires the video to be on-screen or it stops playing, which makes it completely useless for listening to things. Other video sites are much better for this. (I don't need advice on how to get around this thanks, I already know how to. But that's another of YouTube's crappy standard behaviours.)
