i'm actually surprised at the placement of some of these, particularly a/b/o being at number six, because i had never even read an a/b/o fic until last year, the year before? even though i started reading fic back in 06/07! on the other hand, i am absolutely not at all surprised by the first five because found families, loyalty kink, fake relationship, spy au, and seemingly unrequited pining are my faves. also this was strangely difficult? but that may just be because i'm an extremely indecisive person.

if you do it, let me know! i'd love to see your results (and see how similar/different ours are).
