It's not so much about what you like (though it boggles my mind that people might be here that don't care for vampyres and the women that slay them). It's just about what got you here.
Ah- that makes a lot of sense.
What got me here was the premiere of Wonderfalls. I was curious about it since I enjoyed the pilot so much and was already in pre-mourning for the loss of Buffy and Angel and Firefly, looking for a new show to love.
I googled "Wonderfalls", and one of the links that showed up was to the Minearverse. I poked my head in, lurked a little, and by chance, Tim was actively posting at the time. Seeing the interaction between the writer/producer and the other posters fascinated me. I posted a couple of things, got a positive response, got pulled in even more, and next thing I knew, I was sending Allyson money to help Nilly (who I did not know at all at that time) come to the USA.
Basically, I got incredibly lucky, timing-wise. I am very careful about over-committing myself generally and was not looking for another obsession. But...the Buffista love and snarkiness and intelligence and humor was so overwhelming that I stayed up all night and basked in it. As I stumbled into bed at dawn, I had one of those rare moments of clarity in which I knew that my life was somehow going to change profoundly as a result of the relationships I was about to form.
It already has. Seriously, not being melodramtic here. And know what? I feel strongly that I haven't even started to see the extent of the effect it will have in my future life.
