After cursory perusal of the comments here much deliberation, I have settled on my choice for the 2005 No-sword Kanji of the Year. It is:

蔀

Containing elements from both of the "if not this year, then never" kanji on the shortlist -- 郵 (as in postal service) and 萌 (moe) -- it elements elephants the need to choose between them. Kicky, sexy, and archaic, its kun reading is shitomi, a kind of shutter to keep the wind and rain out. Learn it, live it, love it.
