website - Bret Victor's explorable explanations
http://worrydream.com/ExplorableExplanations/
An link not tracked asks questions, considers alternatives, questions assumptions, and even questions the trustworthiness of the author. An active reader tries to generalize specific examples, and devise specific examples for generalities. An active reader doesn't passively sponge up information, but uses the author's argument as a springboard for critical thought and deep understanding.
