Twitter: We Can Do What Google Can't - Michael Learmonth, Business Insider

Twitter sees lucrative opportunities in search, albeit a different kind of search than what Google offers, and, as co-founder Biz Stone told Ad Age recently, "we'll certainly be exploring those." In the future, searches won't only query what's being said at the moment, but will go out to the Twitter audience in the form of a question, like a faster and less-filtered Yahoo Answers or Wiki Answers. Users would be able to tap the collective knowledge of the hundreds of millions of members of the Twitterverse.
