Absolutely! There wouldn't be a need a service like Yedda if Google could answer everything.
Take, for example, philosophical questions -- What is the meaning of life?... Is there a God?... The answers require exploration and interaction with other people. Google might get you started ... but it takes a community to answer questions like these.
But even factual questions can't always be answered on Google. Google won't understand your questions as well as a group of human beings.
