Can we have some stats when the event is over? Like:
- How many people completed the challenge and how many finally got the hat (those who tried it, but didn't have an account on MSE)?
- Which was the hardest and which the easiest question?
- What was the average response time?
- How many wrong answers were for each question?
- How many users stuck in one question and didn't manage to save the unicorn?
- How many people got rickrolled when they tried to cheat?
and of course, whatever else you think is interesting.
