Hitwise研究中心主管Leann Prescott给出了一份美国question and answer市场中各网站的占有率统计结果，其中Windows Live QnA位居第三，但它1.02%的市场占有率与第一名Yahoo! Answers的96.10%相比，实在相差太多。

来自WL QnA官方Space的消息，Windows Live QnA在今天开始公测了。让我们来回顾一下WL QnA都有哪些特色：

- A smooth interface that enables you to ask, answer and vote on a question.

- A free-form “tagging” system that allows you to attach your own keywords and phrases to your question to make it more discoverable by other users. With QnA, you tell us what the question is about, not the other way around!

- Integration with Windows Live Spaces via modules that show off questions you’ve asked and questions you’ve answered.

- See your score constantly increase on the Superstars page and earn reputation stars for consistently giving great answers.

- Windows Live Messenger “gleams” that show when you and your buddies have participated in QnA.

- Email notification that someone has answered your question, or when others have voted on a best answer, via MSN Alerts.

- Ability to tag embarrassing or “adult” questions with the “mature content” tag – which keeps explicit content away from those who don’t want it

- Ability to subscribe to a customer, question or site search via RSS.

- Message boards that let you get support information, discussions with other people, and contact with the QnA team. You can’t chat or discuss things in Windows Live QnA without breaking the format… so instead, go to our message boards. (http://boards.live.com/qnaboards/forum.aspx?ForumID=17)

- You can always find news and updates to the service on this blog, http://liveqna.spaces.live.com!
