Aaron Goldman shares some thoughts on Microsoft's new "decision engine," Bing. While several search engines have already been labeled "Google-killer," it's important to note these engines have attributes that could complement instead of send Google packing or reverse its dominance in search. Goldman does, however, point to several Bing features that outshine Google's.
