I knew the basic premise of the show in question but didn't know enough to actively dislike it (in other words, unlike some fandoms I hadn't suffered from people lecturing me about how I must get into the fandom in question, or how it was the greatest thing since sliced bread).

I don't think there were really authors I knew from elsewhere because my view of fandom was pretty limited to SG-1 (and UNCLE, to a much lesser extent because it tends to have more single fandom peeps in it)...
