One way to dream up post-book media to make reading more effective and meaningful is to systematize "expert" practices (e.g. How to Read a Book), so more people can do them, more reliably and more cheaply. But… the most erudite people I know don't actually do those things!
Yeah, it's a difference of personality (brain) type. Some are aiming to copy the ideas on offer, while others are looking to play with them and combine them with ideas already collected, to generate totally novel ideas. The creative types take notes only when they are inspired.
