I'll go against the grain and say that fumbling is how you learn. The easier it is to get to the end of the tutorial, the less you learn in the process. If you learn math from a bad book, you have to organize your own notes, to untangle the mess. If it's laid out all neat and clear like a straight highway, you never wrestle it out with the concepts and you don't learn.
That's something I came to accept as well - deeper understanding will only come from challenge. Unfortunately, there isn't always the opportunity to let people fail, and that opportunity is definitely not in a set of reference docs.

Okay, but GP is talking about tutorials, which are a completely different form of documentation.
