Not mine. The information per unit of time is so low so my mind start to drift or I start doing something else and forget about the video. Much prefer text that I can skim and find the parts that are relevant to what I need to do and simply skip the sections that seems to be most fluff.
If only someone did ctrl+F for video.
I do this on youtube and things like treehouse. The reason I tend to watch youtube on my tablet in the browser and not the app is because the app doesn't allow this and my brain goes numb.
That having been said, I really love video for some things. For example, I'd much rather listen to Greenwald's speech at Brown on civil liberties than read the equivalent article. I tend to clean my room or play Pro Evolution Soccer while doing so and somehow that works brilliantly. I can't quite keep the same concentration when I read for 30 minutes.
But it really depends. If I want to look up some code documentation, that format is a billion times better in text than video. If I'm somewhat familiar with the topic, know what I'm looking for, the ability to easily skip over introductions, side topics and history and just Ctrl+F for e.g. a piece of code, it can save an order of magnitude of time. I tend to like videos for things I'm wholly unfamiliar with and want to listen to from start to finish, which frankly is pretty limited.
There's also the people that like having videos running while doing something else. I find this to be a disturbing habit, especially when it's done advertisement laden TV nonsense. But people seem to enjoy it.
Sitting at a computer means that there's about 10 possible distractions for me at a given moment, and if I want to do a consistent stretch of actual work, i just happen to need some background noise.
After I've learned it? Text all the way.
I really think many such videos are a step backward as far as carrying information goes.
