rewrite intro of chap once the whole thing is re-read -> semantic compression and spatial navigation, expression and execution

in the scales part, add that the structure/syntax/vocab framework is the same as dijkstra in “the humble programmer”, quoted in http://digitalhumanities.org/dhq/vol/17/2/000698/000698.html

case studies
    
      - i should definitely have a more comparative approach: multiple code-bases, with aesthetics which are tied to LANGUAGE, COMMUNITY and PROBLEM (question of the idiomatic). this is better than having one case study after another, completely discontinued.
 
      - find similar problems in different programs, see how they deal with it
 
      - find specific cases where the cognitive load is high
 
      - again, DO IT IN PARALLEL as a comparative studies.
