Given the sheer volume of submissions, would you consider letting people volunteer to vet questions in the future, or are you planning to simply stop accepting new questions at some point?
If you were to be ambitious and say each person could process 1 question every 3 minutes, that is still 22ish hours of work per person, and presumably the submissions are growing every day. It looks like there are more submissions now than there were several days a go. I take it trivia questions aren't a priority at this point in development.
I really like the trivia game but I agree that the pool of questions is a bit heavy on anime and games. It's fun being able to submit questions, but I wonder if they'll ever make it into the game, given they are in a queue with 980 others.
