I think that you have maybe answered my biggest question. The geeks who are not solely gamers are feeling Gygax's death because it reminds them of how their lives have changed since (perhaps because of?) D&D. Apparently they are feeling the wind of their own mortality because of his death rather more strongly than I am.
I like your question, though I think a slightly better, though related, question is "What has geekdom become since D&D was first published, and what do we as geeks want to make of it?"
