Tutorials are best for beginners. They start from zero, so the author can build one bit of knowledge on top of another. It's easy for the user to feel progress, because every few minutes a new idea/concept can be introduced and explained (at a high level). It's harder to make a tutorial for an expert. Different experts will know different things, so it's unclear how much time to spend explaining any particular concept. It's harder for users to feel like they are progressing because: 1) it takes much longer to get a "unit of knowledge" across because the concepts are more complex. 2) you are really "filling in the gaps" of stuff they already (partly) know, and they may not even know how many gaps they have. So progress is harder to see and measure. Random brainstorms: - Different people learn different ways. Some people want to learn via audio, some via video, some via text, some via diagrams, some only learn by hands-on doing. - Talking is pretty low-bandwidth compared to reading. That usually includes most video, since it's just video of someone talking, sometimes with a few low-bandwidth slides. - Staring at talking heads is boring. Partner with an artist to create animations and diagrams for your talk. - You could try an "expando" tutorial: One that can give high-level details to novices, and expand into nitty-gritty details for experts. I'm not sure that would work in video, but it could work for text or diagrams. - Or maybe you could try something like "VH1 pop up videos", where a novice could listen to the talk, while an expert could be reading all the sidebars while listening to the talk. - Each of the areas you mention (learning programming, learning kernel internals, etc.) is a world of it's own that would take a long time to make materials for. You could start by re-purpose existing content (technical blog posts, "Open Source Architectures", etc) to turn into a "video explanation". This would be a quick way to get started and see if you have a useful concept.
