Microsoft beta launched their Web "answers" site as Windows Live QnA in August 2006 and it never made it out of beta - MSN QnA will be closing May 21, 2009.
We are ending the QnA beta test and are closing the QnA site on May 21, 2009.
First and foremost, we want to thank you for your participation. Since we introduced QnA, we’ve learned a lot about this new way of communicating and creating valuable content. At this time, we are closing the QnA site, but the experience of running QnA and gathering all of the great feedback you’ve shared with us will certainly influence future product direction.
When QnA moved from the Live Search organization into MSN we announced that we’d be looking for new ways to share questions and answers across MSN and provide new opportunities for you to engage with each other and share your opinions, ideas, and knowledge. That mission has not changed. Questions and answers are still important to MSN and your feedback has been very valuable for our future product strategy. You’ll see more ways of how MSN will empower people to connect and communicate over the coming months.
I must have missed the branding transition to MSN from Windows Live, but then it looks like everybody else did too. The Web answers biz is completely dominated by Yahoo Answers - even Google had to pull out of it - so it is no surprise that QnA had a hard time getting traction.
