This question already has an answer here:
Remember Winter Bash? How fun was that?
I propose that we give a virtual broom to everyone who completes 10 reviews in any 24 given hour period. The broom would only last for 24 hours, so to keep it, you would have to do 10 more reviews the next day.
But having a broom would be cool. It would be a nice visual reminder of those folks who dedicate a small amount of time each day to help us sweep the floors.
