Who said Microsoft doesn't have any friends? 

Twitter and the Redmond, Wash.-based company sent a series of tweets yesterday to publicly announce that Bing and the micro-blogging social network were going to continue their two-year partnership

Bing and Twitter struck a deal in October 2009 that allowed people to see tweets relevant to their search querys. Shortly thereafter, Twitter signed a deal with Google to include relevant tweets in the company's Real Time search feature. Google ended its partnership with Twitter in July and announced it was looking for ways to incorporate it's newly released Google+ social network into its search results.
