Disclaimer: This is not a debate about whether Season 8 is canon. So let's just not go there - we all know how that bit will go (not well..? :) ), so let's not argue the point so as to avoid this death trap, yeah? This is just a discussion about the concept of canon. As such, I welcome all viewpoints from those who would share their thoughts.
So here's a few questions. I'm not going to use a poll because that would be perhaps be more reflective of my own views when I really want to hear other people's opinions. Please feel free to share your thoughts!
1. What is canon?
2. Who determines canon? And on what authority?
3. What purpose does canon serve (or ideally should serve)? How is it useful? (Or) Why does canon exist?
