I said "complex information". This is vague, but you can see the truth of this in a following way: take any topic, such as maps, which you mentioned. What's more complex, a map, or knowing how to make a map? The former will be a picture, but the latter will be mostly text. As far as I can tell, this is the rule. As you go up in complexity, text becomes more and more suitable. By the way, I mostly agree that books are overrated. The reason is that most books are not very complex. Text is the wrong medium for the ideas of their authors.
