Note: I'm going to be as honest as possible with my answers and include writing I did under another name. There won't be links to those fics though because there is a reason I don't write under it anymore. If you really want links PM or email me.
1 - How did you first get into writing fanfic, and what was the first fandom you wrote for? What do you think it was about that fandom that pulled you in?
I started writing fanfic after knee surgery that kept me home and not able to walk for 6 weeks. I had been reading it for a while and just really needed something to do to keep me busy so I wouldn't go crazy sitting home all the time. My first fandom would've been Buffy. No idea what pulled me into it, it was so long ago (guessing around 2000). My first fics were Buffy/Angel or Buffy/Spike...but I quickly realized I really, really can't write Buffy very well at all. I could write Willow though and I had plenty of Willow/Spike bunnies to write.
2 - Name the fandoms you've written in, and how much you've written in that fandom, and if you still write in it.
BTVS/Angel-- This was my first fandom and by far the one I was most active in. Let's just go with I wrote a lot. I have no idea of the number of fics and drabbles I've done there. I haven't written it in a couple years, but I love this fandom so anything's possible. I wouldn't say I'd never do it again I just haven't had an idea worth writing.
Harry Potter--Second fandom I got into...I wrote quite a bit. Mostly shorter ficlets and drabbles and only a couple multichaptered fics. Again, no idea of the number but it's a decent amount. Also, as with Buffy, I love this fandom and would write it again if I had a story idea I felt I could do justice too.
Torchwood--I wrote 2 multichapter fics (I think) and one was left unfinished when I left the fandom. Would I write this fandom again? No. I still adore the show and have occasional ideas for it but I can't and won't deal with the drama of this fandom.
Doctor Who-- A few drabbles and a Torchwood Crossover is it...and because it is closely connected to Torchwood fandom the answer is no, I wouldn't write it again, for the same reasons.
Charmed-- Just a drabble or two as requests from friends. Probably not, it was never something I wrote other than if a friend requested it.
Anita Blake--a Buffy Crossover and a few drabbles. Not likely, when the Series became more porn than plot I stopped following it closely enough to write it.
Firefly--Like Charmed my writing was mostly by request so drabbles only and not many. And same as Charmed, unlikely to write it unless someone asks.
AI/Adam Lambert--10 fics (or series) And yep, definitely would write more...am writing more. I have two big bang fics I'm working on now. For some reason I don't do well with shorter stories in this fandom and I'm trying not to post WIPs so posting is few and far between.
