I've been trying to think about how to get some excitement going for the ranked quizzes you added.
What if we had ranked seasons that go a month, two months, or several months at which point the MMR/Elo resets and the winners of the previous season are honored. At this point you could also retire the current ranked quizzes and move them to unranked to keep things fresh and prevent people from abusing the system by retaking quizzes or sharing answers.
Thoughts? (this is addressed at everyone not just the admin(s))
