I read an article in WSJ that people like Bing, even better than Google on average, but are not often switching altogether because Google is "good enough". Building a better mousetrap does not always get more mice. That said, in one month, bing.com from Microsoft has increased their search share from single digits to over 20%. I like bing; alternative refinements to search in left hand column automatically, and mouse over any video or image (in video and image searches) and it previews what else is on that webpage without having to click it/go to it. Sweet.
Have you binged today?
