Personally I find video tutorials USELESS. I can't learn a blasted thing from them and they are more of an annoyance than anything else. In fact I watch people try to learn from them and shake my head as not only are the tutorials more often than not wrong, the person in question COMPLETELY misunderstands what LITTLE information is present.
They waste five to ten minutes on concepts that don't even warrant a paragraph of text, they're near impossible to search or cross-reference, often the resolution makes it so you can't even read what little text is present, you waste time on trying to figure out what the different accent or bizzaro-land pronunciations are even trying to say, and on the whole the result is a hot wet sticky useless MESS.
Gimme a book, a website, the actual specifications -- TEXT!!! Then I'm happy.
MAYBE it's because I learned computers some two decades before video tutorials were even a thing, but I don't "watch" tutorials.
That or it could just be my utter lack of tolerance for the TLDR "wah wah, I dunz wanna reads!" mouth-breather twitter-generation, who I imagine just yum up the video tutorial crap.
Hence why when someone asks "what do you think of my video" the first words out of my mouth is "Do you have a transcript?"
