Yesterday, I posted a brief reply to the anonymous moderator of the brand-new myoldfandom ficathon, which is gearing up for its first event. ("Old" = no new canon after 2005.) So far, it sounds like an update of oldschoolfic, which I enjoyed a lot. But I really know nothing at all about myoldfandom or the people behind it (and I'm just a little nonplussed by the modly anonymity).
All my own dearest fanficly fandoms qualify, of course. FK, HL, YB, BSG78, D&DC. Probably even the Buffyverse qualifies, although the comics do purport to be canon. It's not that I don't watch and enjoy new series! I'm all over Agent Carter, Once Upon a Time, Person of Interest, Poldark, Call the Midwife, etc. I loved Forever while it lasted, and Grimm and Sleepy Hollow before they jumped their sharks. But of course they aren't — for better and for worse — the same as stories loved long and long and long.
I wonder whether rarelywritten is planning a round this year. If so, I wonder whether the schedules will conflict or complement.
