A Top Contributor is a member of the Answers community who has shown that they are knowledgeable in a particular category. Each Answers user can be a top contributor in up to three categories.

The top contributor badge is dynamic —you earn it or lose it depending on your recent participation in a particular category. The more actively you contribute, the more likely you will earn a badge. Just like featured users or category leaders, it's another way to feature community members who might otherwise be overlooked.
