I suppose you're one of those to persons that need illustrations in your books to fully comprehend too.
I don't read books. I find them unnecessary and time consuming. I can look at one diagram and understand the content just as much as, if not more than, people who read words based in the same content matter. Reading introduces the possibility of miss-reading and misunderstanding information, which consequently can lead to confusion. Diagrams alliviate the possibility of these errors (at least for me) and (again, at least for me) the diagram can be fully memorized at that moment with a mental photograph, unlike words.
So yes, I appreciate diagrams more than words because I can more quickly absorb the information graphically than verbally or textually.
Your tone of text (voice) seems to be somewhat pretentious in that you portray those who learn textually are superior to those who learn graphically. Science has shown that both formats for learning lead to advantages and disadvantages in life, and that neither style of learning is, indeed, superior. The only reason you feel superior is because our entire education system is textual because that is how we have been doing it since the beginning. Security in familiarity should not be good reasoning for a 'suprematic' attitude.
