Google may have a huge lead over its competitors in terms of market share, but the search giant isn't resting on its laurels. A next-generation infrastructure codenamed "Caffeine" has been unveiled, and it's already available for individuals to test.
Fair warning: don't expect Caffeine to introduce natural language recognition, search results from Twitter, or anything else too fancy. Matt Cutts cautioned, "The Caffeine update isn't about making some UI changes here or there. Currently, even power users won't notice much of a difference at all. This update is primarily under the hood: we're rewriting the foundation of some of our infrastructure."
Still, he continued, "Some of the search results do change, so we wanted to open up a preview so that power searchers and web developers could give us feedback."
