Congrats to Moffat on a job well done.
Personally, I'm surprised there was any doubt that "Blink" would win. While Cornell's 2-parter was excellent, think about how many items with "The angels have the telephone box" on it have cropped up. "Blink" latched onto fandom in a way that Cornell's 2-parter just didn't quite manage, and these are the fans voting here.
I would like to see the voting numbers, though. I wonder if it hit four digits?
I would think that the degree to which something from the episode has "latched onto fandom" (and you mean "latched onto
by fandom," surely?) has less to do with what should get a Hugo than the actual quality of the writing, right?
Not that I disagree; as good as "Human Nature" was, I think "Blink" is even
better: more concise, more emotionally engaging (and again, in comparison to "Human Nature," that's
saying something), and it manages superbly the difficult task of being an episode of a television series in which the lead character barely appears, but still manages to make his presence felt throughout the episode.
