I'm not a member of the NYT online so I can't reread it right now, but I did read the article earlier this week linked to another site. Isn't the title of that one "The Genre Artist"? And isn't it basically about how unknown/unappreciated he is? I remember a quote about how if he was from another country he'd have won a Nobel Prize for Literature (do they really give out one for this?), but since he was American nobody cared (very vague paraphrase of course, since I only barely remember the quote).
Yes, that's the one. My point wasn't to refute that he was more obscure than someone like Tolkien or Salvatore, only to refute the idea that he is only discussed among Dungeons & Dragons nerds on messageboards.
That is simply not the case.
