Hugo Awards discussion post: Campbell, and long-form fiction categories

This is my last post dedicated to discussion of the Hugo Awards finalists. Voting closes in a few days' time, and it's been great to discuss the nominees in this, my first year of voting. As always feel free to join in the discussion in the comments, where I will set up a dedicated thread for each award category. You're welcome to interpret this call for discussion in any way, whether that's setting out how you're planning to vote, offering your thoughts on a single finalist, or something else entirely.
