I was wondering if there could be a Dark Agenda NYR challenge or similar, actually -- I acquired two sources specifically to write treats, but got them so late that it never happened for this year. (This was partly because signups and therefore yuletide letters went out late, I think, because I started looking for one of them basically on signup day!)

I also echo yhlee's comment about source familiarity -- I wonder if there could be a series of posts before nominations, even, for people to enthuse about their favorite chromatic sources?
