Whee.
Let's see. I'm a full-time undergrad who double majors in English and Creative Writing. I work mostly with fiction, and my long fiction is pretty much exclusively fantasy. (Of course, my "long" works consist of an 11k word novella, a novel that's halfway through, and two novels that I have yet to write.) I used to think of myself mostly as a novel writer but lately I've become enamoured of the short story form, as well. A lot of my short stories aren't fantasy at all, but tend towards liter- umm, something that is not literary fiction, because to say that myself would be pretentious.
I'm doing NaNoWriMo for the first time this year, using it to work on my current novel, which you guys probably won't be seeing, because the first eight chapters have already been workshopped to death and need significant revisions, and it would be silly to give you chapter nine. I will be getting started on another novel in December (here's hoping I can finish the first one first, don't really want to be working on two at once) that's related to the novella I mentioned before, and some of that you guys might end up seeing. Until then it'll probably be short stories from me.
I also do some songwriting and playwriting. In fact, a couple of my major projects this year will be a musical (hopefully) and a story album thing. If I knew more about those, I'd tell you. I have a lot of work to do
As for WHY I write what I write, genre-wise? I have no idea. I just tend to go with whatever fits the story best, and lately I'm finding that I have some things to say that don't have to be speculative fiction, which is why so many of my stories end up as, umm, mainstream fiction.
