I don't expect much (at least I don't think I do).
I expect a quality run platform where questions and answers are judged on their merits alone. This is something musing seems to excel at. Very little personal bias that I can discern at all.
I expect them to monitor and take appropriate action against spam, illegal or unwanted content. I would like to see more action against repetitive questions but that is a tall order and is a want, not an expect.
Other than that I don't expect or demand anything. This is their platform, they set the rules, the rewards and how long it operates. I will simply partake and be grateful for as long as they allow it.
