Right, you need to learn by doing and cannot just passively watch a video or read a text. To learn a topic like programming, you need to practice it. So a good format is to combine a text with small questions and coding challenges. If the user is unsure of how to solve something, it's easier to look it up in the text they read than in a video they watched. And hopefully they'll recognize that the question is asking something they can answer on their own without emailing the author. (Though once the text is online, there should be some kind of forum there to ask questions anyways.) (PS - I'm actually looking for programming authors or bloggers who would be interested in publishing online with questions and programming challenges.)
