I really wish YT would drop the 10 minute cutoff for mid-roll ads. It's a destructive incentive to the platform. Let creators put ads wherever they want on whatever length video they want (within reason and with abuse checks). Then you won't get 7 minute videos with 3 minutes of added fluff just so they can be better monetized.

And we can ignore creators who over-monetize if we want (or buy Premium or use adblocking).

> The Wadsworth Constant is the idea (and 2011 meme) that one can safely skip past the first 30 percent of any YouTube video without missing any important content.

I heard about this a few months ago, and have since checked when the actual content starts in the videos I watch. I certainly can't agree with 30%, usually in 15-minute videos, the introduction is 1-2 minutes before they go into the meat. The bigger problem is all the filler, sponsorship breaks, "remember to ring the bell" etc., that occur at seemingly random points, though I don't think it adds up to 30% filler even if you count all that. Maybe I just skip over most of the garbage.

> And yet YouTube videos themselves are approximately 30% non-content.

That's "non-useful" content rather than "non-content", those 30% are intro and filler which you might also find in non-youtube content. And obviously it also depends strongly on what kind of content you're using youtube for. Skipping the first 30% of a recital is probably going to skip interesting content.
