A lot of comments in this thread make it sound like if you're not going to perform rote memorization of what you read then it's not worth reading at all. Learning is more than memorization. To simply write-off all knowledge as just regurgitating facts is exactly what's wrong with the modern education system. Read for the sake of reading, explore new ideas and grow.
Any chance you have a blog post referencing more of this?
I have gone the way of markdown + git + vim a few years ago but your model seems a bit more hierarchical and organized.
