Not sure about others, but I almost never watch video content to learn how to do something with a computer. I don't like needing to have audio turned on, they are often either too slow or too fast, and they don't allow me to move at my own pace / jump around as easily.

Video is a great medium to convince me to try something or show me why I should do something a particular way, but not the medium I want to use to learn how to use a thing generally. Really prefer text and occasionally text+picture.
