For Mr. Walk, director of product management at YouTube, the competition is not other Web sites: it’s TV.
“Our average user spends 15 minutes a day on the site,” he said. “They spend about five hours in front of the television. People say, ‘YouTube is so big,’ but I really see that we have a ways to go.”
1. Content is not compelling. Most of the viral videos are amusing but trivial curiousities. It's like eating donuts or potato chips--briefly enjoyable, but in the end, largely a waste. In other words, different from, but intellectually and spiritually comparable to, broadcast TV. And I happily gave up broadcast TV about the time I started driving.
2. Production values. I love HDTV. Love it. I pretty much won't watch anything in low-def, there is just no reason to. So why would I want to watch ultra-low-def YouTube?
3. Living-room factor. I spend SO much time in front of a computer, I really don't want to increase that amount. So when I read, I would prefer not to read on-screen (I often print articles for off-line reading). Same with watching stuff--I really much prefer to watch on my nice, big-screen, high-def TV in my comfy family room.
