Yahoo Answers: Ask and Ye Shall Receive....

Yahoo has launced a new service that looks like an interesting way to share brainpower. Yahoo Answers is a simple concept: You ask a question and categorize it in a topic, making it easier for others to find and answer it. Your question is posted for others to answer. Once your question is answered, select the best answer, or have the community vote for the best answer.
