The content on YouTube is really tremendous. I have used it to watch tutorials for fixing a food mixer, replacing my minivan's factory radio, painting miniatures vikings and ultramarines, learning boardgames, and refreshing some math theory. I have used it to watch documentaries and fan-made movies. I have listened to audio books. Sometimes, I even listen to music and other forms of audio & video performances. Unfortunately, the interstitial advertisements are beginning to kill YouTube.
I accept the need for YouTube to generate revenue with advertising, and, as crazy as it sounds, if the ad is short, I let it play through rather than take action to skip it. What I can't accept is the jarring interruption of the interstitial ads. You are listening to a 7 minute recording of a live performance. The performance beautifully builds for the first 3 or 4 minutes and then, just when it reaches a crescendo, an ad for throat lozenges breaks into the middle and ruins the whole thing.
I will continue to use YouTube as it has so much content useful in my daily life. I am going to skip most everything else until they replace the interstitial ads.
