I actually have one for today and nearly forgot.
cassiopeia7 asked what my first fandom was.
In real life, long before the internet existed (well, it might have been in its infancy as that military thing it started as) there was this Japanese giant robot show and I was eight and fell in love with the kid star and, well, Laure Alexander's story sprang from that. At eight. *snort* I was always imaginative. At fifteen I took the bones of those memories and created Laure, then I threw her into the Legion of Superheroes and then the X-Men.
So, I guess, technically those were all fandoms with a Mary Sue (and there were also the hundreds of pages of Star Wars stories which is how I met
nursedarry and some M*A*S*H stuff.)
But, really, my first fandom was Buffy. Around eighteen years ago nowish I joined my first email list ever--bbeta--and shortly thereafter I posted my first chapter of "Lily". (And now I feel very old.) I was very active for a couple years--not just writing fic, but posting on forums and running email fic lists. Back then all fandoms were tiny, even Buffy. When I started writing, there was ONE major archive and a handful of personal fic sites. There were maybe fifty writers and only a few hundred stories.
Man have times changed.
Four seasons of Teen Wolf have produced over fifty thousand fics alone, and probably thousands of authors.
But, you know, that fandom and many, many others probably wouldn't exist in the huge way they do if Buffy hadn't exploded all over the internet in the early years. I think it was probably one of the first biggies.
Over the last eighteen years I've dabbled in other fandoms but I've never written as prolifically as I did in Buffy (not even in Teen Wolf) and have never been as active in the fandom outside of writing.
And, as I've said many times, I wouldn't be here now typing this without Buffy (and me getting up the nerve to actually post something).
