http://qna.live.com/Microsoft has launched Windows Live QnA, an ask-a-question-get-an-answer site in the style of Yahoo! Answers and Google Answers. The site, currently in beta, relies on a reputation system whereby good answers (as determined by the question's original poster) increase your "score." It's got plenty of Web 2.0 trappings, including tags and integration with Windows Live Messenger (in the form of your Messenger contacts being highlighted), and there's a "Superstars" page that shows which users currently have the highest score. Microsoft Program Manager Betsy Aoki describes some of Windows Live QnA's more interesting features and gives some tips on how to garner the best results on the service's official blog.
