My entire YT browsing is based on already knowing what I want to watch. I proceed to search and hope that the video is what I am looking for. No previous info about quality, content, anything.
Sometimes I have no clue what I want to watch, I just feel like watching something. Back in the day I would flip through channels until I was caught by something.
YT should have a discover mode that is similar to navigating through channels on the press of a button. Maybe give me some filters and then let me "peak" into videos.
Of course the experience is hard to implement when providers are throttling YT traffic. Flipping through channels would then suck, because the video would take 20 seconds to load all the time.
But yea, that's why I don't use it like TV. I use it more like I use Google Search. When I just want to know random interesting things without knowing what I want to look for, Google Search is not that helpful.
