I did go with AO3 stats, largely because of how drastically my comment count went down when I closed off LJ comments and linked to DW instead. Otherwise, the list would probably have been weighted towards older stories.

This makes me sorry that I'm unfamiliar with the Magnificent Seven canon.

I think that one stands relatively well alone, as most of the story is told in flashback, but milage may vary. It's about two men mourning their lover, who has recently died, and trying to figure out whether they can still be in a relationship without him holding them together. It's mostly my favourite because I was revisiting the fandom of my adolescence as an adult and likewise nudging the characters a little further down the road to say goodbye.

Sometimes I wonder what it would be like to write a juggernaut pairing in a hugely popular fandom (ironic, I realize, considering that HP was a megafandom and even lesser known ships received far more feedback than fic in the vast majority of other fandoms).

I've wondered that myself, and I've been startled the handful of times I've wandered into juggernaut pairings or fandoms of the moment (yes, HP was hugely popular, but it was so spread out chronologically and in terms of interest that it was really more like an archipelago than a land-locked country).

However, I've largely stopped even trying to guess what makes a story popular. My most-kudos'd and clicked fic under this pseud on AO3 is actually a Tintin one, at about twice the responses of Father to the Man. And that's not even touching my Hobbit fic, which has some very odd stats.
