24. Oy. Sounds like the killer whale/SeaWorld fandom. When I started in it years ago, there was one or two websites and a small crowd. Now it's HUGE, and the fangirls scare the piss outta me. Having gotten into the marine mammal care/zookeeping industry myself now, I find myself reluctant to mention it outside my own LJ because it brings on scary, rabid fangirls.
