Microsoft’s revamped Bing search engine has harnessed the power of Twitter to enhance the relevancy of the engine’s results.

The Redmond outfit has confirmed that a select number of prolific Twitter users are currently being indexed in the experiment.

“We’re not indexing all of Twitter at this time… just a small set of prominent and prolific Twitterers to start. We picked a few thousand people to start, based primarily on their follower count and volume of tweets,” wrote Microsoft Search Technology Center GM Sean Suchter. “We think this is an interesting first step toward using Twitter’s public API to surface Tweets in people search.”

The initial roster of Tweeple is designed to appeal to a broad range of unique interest groups; provided examples include Danny Sullivan, Kara Swisher, Al Gore and Ryan Seacrest. We can infer that Microsoft hopes to interest the critical Digg regurgitator, chatty Cathy, washed up politician and squealing fangirl demographics with these selections.

Suchter also encouraged users to follow Bing on Twitter.
