Microsoft seems to have decided that this week is “roll out new features” week for its upstart search engine Bing. Yesterday the search engine infused new features into Bing Maps, and it also transformed MSN Video into Bing Video. Today is no different. The search engine has just launched a trio of new features, headlined by one major addition that has been in the works for months: integration with the Wolfram Alpha Computational Engine. For those who may not remember Wolfram Alpha , it garnered major hyped as a potentially new form of search.
