> If a video isn't worth waiting 10-60 seconds for, is the video even worth watching?

I won't know that until the video starts playing. I'm not watching a 90 minute movie here and I don't know if the video I'm about to play is the one I want. Spending a minute setting up a 90 minute movie is very different than spending a minute waiting for a video to load that I'm likely going to spend <30 seconds on.

Maybe I'm learning how to use certain software and I'm trying to find a video that demonstrates how to use a specific feature. In that case I might be clicking through 10+ videos to find the niche thing I'm looking for. If I was just vegging out on Youtube this wouldn't bother me nearly as much.

And don't forget that the time penalty doesn't only apply to the initial load, it would pause and fake-buffer every time I jumped around the video.
