(Although it says nothing about quality and this counts as one)
You can see who the top posters were in previous months by clicking on the month and year. Month also has an option for All so you can see the summary for the Year.
By the way, you can get to this by going to Quick Links in the navigation bar over on the right and it's under Miscellaneous.
