Personally, I don't understand everyone's obsession with youtube tutorials. Yes, they are often helpful and people who record them are heroes. But it's such a waste of time - watching a 10-20 minute video while reading the same tutorial would only take a couple of minutes. Even if I skip to the end, I often have to return to random parts of the video trying to find the pieces of information I need. Ugh...
Well, if it's not your cup of tea, then so be it. Different people have different learning styles. What works for you might not work for others. (Yes, I'm aware that you used the word "personally" and it's only your opinion. )
What's my opinion? I'm glad you asked.
IMO, I think the obsession with video tutorials is because most of the younger generation are more of a visual learner. Some can't grasp the concept of an idea unless they actually see it in action. Maybe it's their lack of focus?..I don't know. Also, video tutorials are more in abundance than written tutorials. That's because many of the ones making the tutorials are lazy and would rather record themselves doing something than taking the time to write down what they're doing. There also wouldn't be so many if there wasn't a demand for them. So, that's a good indicator as to what most learners prefer.
But, FWIW, I do agree with you. I would prefer a written tutorial ( also, a few screenshots wouldn't hurt) over a video any day. As you said, it's much easier to locate a specific piece of information than to keep hitting the fast-forward or rewind buttons. I only mentioned it because I'm assuming that's what the OP prefers, based on his post.
