However, I had to comment on the "Yuletide now sponsored by chocolate" and give a hearty Here Here!

OMG, yes. Last year, my Yuletide writing was fueled entirely by pecans and sugar in various combinations. This year, it was chocolate. So I suspect a key ingredient in Yuletide might be, well, sugar.

Yuletide is apparently what happens if you feed 1000 fangirls a lot of sugar and rare fandoms. Yay Yuletide!
