I'd sort of hard for me to say what I'm interested in - I like a lot of things, but I'm not sure if I like them enough to see events on them. I like Star Wars, Star Trek, Eureka, BSG, Buffy, Angel, and a lot of sci-fi/fantasy authors. I'm not into "hard" science... I'm fairly interested in the writing track. I haven't written anything for 10 years or so, but am curious, I guess, and thinking about trying to write again - would like to learn more about it, at least.
I guess I'm mostly interested in humorous panels or events, regardless of topic, with a slant towards writing/author panels.
