I visit YouTube on rare occasions because I can't find anything else telling me how to do something. The first thing I do is to read the video description and comments looking for a summary, and not actually watch the video. I detest having to watch long video how-tos, as, among other things, it prevents simple side-by-side comparisons and looking at multiple steps simultaneously. Take the work you put into making a good video and use it to make an actual diagram for your diy instructions instead.
I do in fact use YouTube that way: read the notes (or ideally transcript!), sometimes the comments to see if video is worth watching. There are of course cases where video can be useful (showing how to access some part of some device, perhaps) but for me mostly it's too low a ratio of info/unit time.
I do understand that not everybody feels this way.
