I think tutorials, and the culture of tutorials for everything, has lowered the bar for a lot of people, and I have mixed feelings about whether that is good or not. But at the moment there are so many tutorials, they start to duplicate effort. And at present most non text based tutorials aren't searchable without a transcript, and if you have timestamped-transcript you are in luck.
As seasoned users how often do we look for information only to find that the bit we wanted to know was a paragraph or word or a 10 second bit of video of a tutorial. Often we are only looking for the missing information that allows us to investigate further on our own.
For newcomers with no 3d experience it helps to have a narrative, initially. But this need diminishes proportionally to the amount of self-directed effort put into learning Blender (searching and reading the docs, the wiki, the various tutorials sites) until newcomers become intermediate and start to push away the hand holding of tutorials. And they too will start to favour narrow questions and answers.
Newcomers with prior 3d experience tend to be more exact with searches and questions, and generally progress to intermediate or advanced rather fast because they already have the vocabulary or have learned how to learn.
