Definitely interested in this. I think a common problem with a lot of people, even people that are taught from a book, is that you tend to get 'stuck' at the layer of abstraction you first learned. People that don't want to develop their skills leave it at that whereas people that care look a little deeper and say 'oh, my knowledge has some pretty significant gaps...' You can see this sentiment in a lot of the comments: everyone says 'I feel like I'm missing something.' In my case, that realization came after I started doing some hobby electronics projects: once you start seeing how physical hardware interacts it set off a chain reaction where I realized that my knowledge was really deficient as to how you could go from such a low level to the level of abstraction with which I'm familiar.
