Chimera/turtle/gorilla/human, I think. Serial monogamist with the occasional flirtation on the side. Which means that my Writing fandoms are/were XF, Farscape, SG-1 (with a dollop of SGA before the McShep took over the universe). I'll read far more widely, and was a Buffista long before I started writing and posting fic in XF. I'll read lots of fandoms, although I generally insist on knowing *something* about the source, and I have drabbled in Buffy, Firefly, WW, Lost. But my primary/writing fandoms change very slowly. I don't see anything coming at the moment that will suck me away from SG-1, but I know that I've dropped my old fandoms when the canon closed, so I suspect I'll be moving on in the next year.
