Microsoft is currently testing a couple of new features on bing, popups on the search results page showing reviews by Amazon.com or answers from Yahoo! Answers. While, Amazon Product Reviews were integrated into Bing search results few weeks back:
….and the bing team bring Yahooo Answers to bing:
"When your search term is similar to a question in yahoo answers, then you will be provided with best answer, other answers and full question option at the side of the Yahoo Answer search result. When you hover over any of there options, you will be shown with the answers."
The popups appear to show a quick synopsis of the review or answer, and as you can see the Yahoo! answers popup includes "Best answer", "Other answers", and "Full question", all appearing to the right of an answers.yahoo.com search result.
