By now most of have been exposed to Bing's ad campaign, due in large part to Microsoft's huge marketing push recently.  According to a comScore report, Microsoft’s share of search result pages in the U.S., a proxy for overall search intensity, increased from 9.1 percent to 11.1 percent during the time frame of May 26-30 to June 2-6. 

The question is, does Bing have what it takes to build loyalty among users or is it just a pretty shell without much different.  Tom references Bing's differentiators: "Microsoft Announces New Search Engine at Bing.com." 

So, what do you think?  Will it retain any gained market share or is it just a curiosity spike driven by advertising?  Does Bing have what it takes to build loyalty among users?  Please comment.
