For what it's worth, the last time I had a home improvement project I needed youtube help with, the one-and-a-half minute mumble-tronic video shot on a Nokia brick-phone was the most helpful one.

Would I have preferred a nice 1080p, shot in good lighting on a flat white table? Yes. But those also tend to be 30 minutes along, and as you said, with a sponsorship for HurfDurfVPN in the middle.
