I know this thread is two months old, but I am bumping it for a reason:
I think Microsoft has made something that might rival Google in search capabilities. What do you think?
I do not believe Bing will EVER rival Google. They are two completely different entities -- Google is a 'Search' engine whereas Bing is a 'Decision' engine.
Case in point, I wanted to find a portable air conditioner for my house. I decided to try Bing and see what it would do. It produced a page of portable air conditioners that I wanted to look into. When I found the size, BTU Rating and functions I wanted, I looked to see what Bing recommended: Portable Air Conditioners
Being the skeptic that I am, I did a generic "Review" search on Google: Reviews: Portable Air Conditioners
Needless to say, I was impressed with Bing. If anything, Google will be used more because of Bing, not replaced by it!
