The irony is this designer made an excellent demonstration of poor design :-)
i agree none of the graphics use actually seem to mean anything intuitively to me. Looks like just pretty placeholder pictures.
Also if one find oneself writing down 20 general rules for anything, it's an excellent indication one may not have actually grokked the topic because it's very very unlikely you'll apply 20 rules at the same time. It's likely in some situations, 3-4 are important and in other situations, some others are more important and this ability to classify and recognise what applies where is an indication of knowledge and pedagogical strength.
