why people(cubers) do not tell you what they know.
I can only think of 3 reasons-
1- they can't explain it
2- they dont want people to be as good or
3- they dont want peole to know how

I was actually wondering this myself. I've refered about 50-100 students to youtube videos to learn various things and very few come back learning anything. Usually I have to end up teaching them it after school. I've wondered why cubing tutorials aren't effective. Most tell me the person went too fast and they didn't understand anything they were saying.
I've watched alot of them and watched other people try to teach what they know about the cube to other people. I've come to the conclusion that most cubers can't put themselves into the mind of the other person. They skip over steps and take for granted simple things that are hard for a beginner. The bottom line is that just because you do it doesn't mean you can teach it. Most of these tutorials are also by younger people (less than 25) who don't have alot of experience knowing how to teach someone something.
There are thorough tutorials made by some people but they are few and far between. Most people teach something as if the person already understand everything they are talking about. When you teach you need to go about 2 times slower than you think you need to go and usually even this is too fast.
