This is a great idea. The article just talks about taking notes on books, but it's just as worthwhile for movies, podcasts, lectures, presentations, etc.
I've generally found that taking notes during something like a lecture or presentation (anything that I can't pause, in fact) actually hinders my understanding. I think it's because I have to divide my concentration between writing and listening/watching. But for these things, writing up notes immediately afterwards is tremendously helpful.
Sometimes it's just the action of taking notes which provides the benefit, even if you never re-read them again.
