The article itself was very interesting to me. It's got the same kind of tone as a subculture documentary where the speaker is, by definition, outside the group being studied. The surprised fascination with which you tell jokes about Scrabble clocks reminds me of a cable news feature some years ago about a Magic tournament which couldn't get beyond the lingo Magic players invented to describe their games and devolved into a montage of short clips of people saying things that would make no sense to the average outsider at home. "What a mise!" "I'll swing" "In response I'll spin top" "swing" "swing" "mise" "Meloku" "mise" "sealed pool" "Yosei" etc etc. The feature received some amount of praise for being insightful. It just goes to show how easy it is to see another human being as so fundamentally alien that everything about them is but trivia, useless for gaining a greater understanding of the Other. We are all blind and can see no recourse but to complain of each others' blindness.
