I don't understand the draw of video anything at all; I never have. I can read information 100x faster than a video can provide and I just cannot possibly understand why anyone would want to sit through a 45 minute YouTube video that would have taken 1.5 pages of text.
That said, I'm not at all opposed to OTHERS getting the information in the delivery method they prefer. Great; good for you. But! I don't want to see written word be entirely replaced by video. And, before you ask: no; a transcript of the script is not what I want either.
