Microsoft recently launched their new search engine – http://www.bing.com. Initially the word on the street seemed to be that bing is not as good as Google. However, it feels to me that a degree of respect is being now being awarded to bing. It's also the first search engine in a long time that hasn't been completely written off from day one.

Comscore reports that Microsoft gained momentum in the fortnight after launch. Although not conclusive, it is illuminating that interest is building over time rather than simply spiking in the few days following launch.

So how could bing (or any search engine) really impact on the dominance that Google enjoys? Of course the challenge is to provide users with a better search experience (no small task) but apart from that rather obvious challenge what else could disrupt the Google position?
