Zed points to a very real problem - it's easy for us to forget what we know. But there's another problem with targeting beginners. They are all over the place in terms of experience.

Computing is so tightly woven into our world not that it's hard to find people who have more than a passing interest in it who have not find some way to try to code as kids. Even with those who haven't, there's a gulf between people who have tried to do a little HTML editing (and know what a file is) and people who haven't. There's no one place to start. From Zed's description it looks like he's starting from the lowest possible point, but what are the demographics like there? How many people are in that space and are they mostly adults or children?

I think this is one of the main reasons why you don't see much beginner's material.
