Complete list, in posting order, here

Looking back, did you write more fic than you thought you would this year, less, or about what you'd predicted?
More. But I feel like I'm starting to stall.

What pairing/genre/fandom did you write that you would never have predicted in January 2007?
Prison Break: Um... slash?
A few fics for The West Wing

Did you take any writing risks this year? (See above for unexpected pairings, etc.) What did you learn from them?
See above. And I mistreated the English language by translating/writing in English (God Bless beta-readers, by the way).
I can write a wider range of things than I thought.
I will never write a decent story about The West Wing (the series scares the hell out of me and my TWW fanfics are mostly crap). But I'm glad I was able to come up with something.

Do you have any fanfic or profic goals for the New Year?
Completing a few fanfics that I began to write *cough* a while ago. Wishful thinking.

Favorite story of this year:
Hémato-logie / Hemato-logy

Best story this year:
Let's say that the more polished ones are probably Au fil de l'eau / The Time They Need (Michael/Sara, Lincoln) and Clair-obscur / Twilight (Michael/Lincoln). Both of them written for fic exchanges in French. Both of them longer than my usual stuff.

Story most underappreciated by the universe:
Hémato-logie / Hemato-logy. But maybe this is just the fact that I'm really fond of this one and was hoping for more feedback :-p

Most fun story:
Fun to write or fun to read?
Fun to write, I'd say Elle sait / She Knows (Marilyn's POV on Michael)
Fun to read, I'm not sure it's mine to tell, but maybe La Manoeuvre Tancredi / The Tancredi Maneuver or Duckie (English Duckie this way).

Most sexy story:
I hate this kind of question.
In French: I'd say Faux pas : Contredanse but I think it's a rather depressing one, actually. So maybe Entre les lignes. Nothing graphic: sort of a Michael/Sara/Tattoo ménage à trois ;-)
In English: Mileage (Michael/Lincoln)

Story with single sexiest moment:
I still hate this kind of question. And I'm not very sure about the 'single' part of the question but well...
In French: Scène coupée 4 in Vous revoir : Writer's cut or some paragraphs in Clair-obscur - matter of taste.
In English: Probably some paragraphs in Twilight

"Holy crap, that's wrong, even for you" story:
In French: It's really a toss up between Petites histoires qui ne seront pas écrites (all kind of pairings, crack or more serious ones) and Elle (fluff, fluff, and a bit more fluff)
In English: Valentines (fluff, fluff, and a bit more fluff there too)

Hardest story to write:
Tacitement / Unspoken. Michael and Veronica gave me a hard time.

Easiest story to write:
In French: La Manoeuvre Tancredi / The Tancredi Maneuver or Caroline à la Maison Blanche / Caroline at the White House
In English: Let's Talk About Sex

Biggest Disappointment:
In English: Probably Reality Check. But it may be bad memories because I posted a Michael/Sara PWP a week after Sara's head had been choped off - killed the mood.
In French: Inventaire. alohomoraa did a wonderful beta job, but the fic still seems awkward and... not as I wanted it to be.

Biggest Surprise:
The Weaker Position. I wrote Michael/Mahone slash. Sort of. I still can't believe it.

Most Unintentionally Telling Story:
Caroline à la Maison Blanche / Caroline at the White House
Since it's not unintentional when you do it on purpose... I'll go with Mamans / Mommies.
