i'm not the target audience, so my reaction might not count, but...
teaching something is hard. each audience member probably learns in a
different way. for myself, i like to have more of a light theoretical
explanation, something along the lines of the Expression or
Extensibility Problem cf.
listening to WhyHowObjects S1P1, it is too hand-wavey loosey goosey
for me. having said that, if i imagine some really crochety grizzled
stuck in the mud coboalistaz, i can see how the presentation could be
a good hook. :-)
