1. Mother Tongue (723 hits, 17 kudoses (kudos? kudis?), 7 bookmarks). Star Trek (could be either TOS or 2009). In which Amanda pwns disapproving in-laws. I like this ficlet, but it's pure fluff dashed off in a hurry, and I'm rather surprised this is my top fic.
2. And after darkness, light (719 hits, 20 kudi, 10 bookmarks). Narnia. What happens if an Anglo-Catholic decides it would be a good idea to write a Problem of Susan fic. I'm not surprised this one is high-up (despite the possibly off-putting tags, but you can't say they don't warn you what the fic will be like). I think it may be my favourite of my fics, though. I also note that, though more people have _read_ Mother Tongue, more people like this one, as far as one can tell. I think this is fair.
3. In the Files (659 hits, 31 kudi, 3 bookmarks). Deep Space Nine. Behold the awesome power of Yuletide, for this was only written this Christmas. I'm fond of it - I wanted to look at mothers and daughters and the competing claims of various duties, and I also wanted to write something that you can imagine working as an episode (though of course it would need a lot more complications, and a B storyline. Also, I have a suspicion people are more generous with the kudos button at Yuletide.
4. Trailing at some distance, Tell Beauty How She Blasteth (429 hits, 10 kudi, 2 bookmarks). Wimseyverse. AU-fic of doom, which is the most depressing thing I have ever written. This was fairly widely recced at the time (including on TV Tropes), but it was posted on LJ long before I posted it at the AO3, so I strongly suspect that this is actually my most recced fic over all. I also think it's one of my best.
5.In Search of a Big Picture. (375 hits, 18 kudi, 1 bookmark). Vorkosiverse. This one was fun to write, but I can only attribute its popularity (it's a drabble!) to the fact that the Vorkosiverse is a small fandom which is very active on the AO3
And I note that all bar one of my top five fics are female-centric. I find this cheering.
6. Putting on Civvies. (367 hits, 6 kudi, 5 bookmarks). ST: 2009. Pure fluff, with a bit of linguistics geekery, in particular my fascination with the curious use of the Quaker Thou in Amok Time. A sweet little fic, in its way.
7. The Exercise of Virtue. (321 hits, 9 kudi, 3 bookmarks). Bible (NT). Actually I think this is the weakest of my three NT fics, but it continues a pattern of my female-centric fics doing best. I also suspect a pattern where people are more generous with kudos in small fandoms.
8. A Child of Our Time. (290 hits, 17 kudos, 2 bookmarks). Doctor Who. Another one I just dashed off: a timey-wimey origin for Susan. Fairly good idea, wish I'd been able to think of more than a fragment...
9. Some Secrets in a Privacy Forever Ours. (279 hits, 7 kudi, 3 bookmarks). Bible (NT). This one is my favourite Bible fic.
10. Just Good Friends. (278 hits, 3 kudi, 1 bookmark). Star Trek: 2009. More pre-ship Spock/Uhura.
Honourable mention for the great achievement of fic no. 12, Like a Thief in the Night - another undoubted beneficiary of the Yuletide Effect - since it was only published last Christmas, and I am the only person in the world who writes Rev fanfic (NB I would be very happy to be proved wrong).
Do I know what to make of this? No, I don't, other than that I am not and never will be a BNF (but then I don't want to be). Interesting that it tends to be the fic with women at the centre that do well, though.
