"Social discovery tool StumbleUpon has inspired 25 billion clicks by directing people to pages accross broad topics like \"art\" or \"fashion.\" Now it's taking its recommendations to a more specific level with a new feature it launched on Wednesday.\nWith the \"Explore Box\" feature, users can Stumble pages related to hundreds of thousands specific topics \u2014 like Vincent Van Gogh \u2014 instead of working within about 500 set categories \u2014 like art \u2014 that StumbleUpon has stuck to in the past. It's as though a search engine and a \"best of\" list had a child. If StumbleUpon hasn't sorted the exact term you're looking for, it will match you with the next best thing.\nRight now the feature is restricted to a small search bar in the browser product. But despite the minimal presence on the homepage, it's a huge change for StumbleUpon.\nIn the future, StumbleUpon CEO Garrett Camp says, StumbleUpon will integrate Explore Box's technology with its follow feature so that users can Stumble a mix of general and specific topics. That will make the discovery engine a lot more personalized, and eventually (though Camp says probably not anytime soon) enable StumbleUpon's advertisers to more closely target their ads.\n\u201CWe\u2019ve had to basically rewrite the recommendation engine,\u201D Camp told Mashable. \u201CEven though it seems a lot of work going into one feature, that one feature is going to influence the entire experience.\u201D\n\n\n\n\nPhoto courtesy of Flickr, Laughing Squid"^^<http://www.w3.org/2001/XMLSchema#string>
