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.
