Why doesn't Answers.com control the quality of answers posted on WikiAnswers?

WikiAnswers QualityAnswers.com is the overall brand for the website that brings you answers about anything. It's comprised of a few parts, and when you ask a question, you may get an answer from either of them: ReferenceAnswers is where you'll find referenced, reliable information from established sources. WikiAnswers is different. On this site you ask and answer questions yourself. The answers come from volunteers from all over the world. As a volunteer wiki, the community controls the quality.
