It can be about a canon you know I'm familiar with and into fannishly, a canon you know I'm familiar with but haven't seen me do much with fannishly, a canon you don't know if I'm into, or a canon you know I'm not familiar with but know that I've heard about.
It can be as simple and specific as "which do you prefer, A/B or B/C?" or as broad as "what are your thoughts on yaoi?" (although this is boring and I'm sure you can do better) or as complicated as, "tell me what you think about the implications of Theory X for the themes and characters of Canon Y."
