Maybe Google needs to take the final step in this evolution.
Let's have Google show nothing but quick answers, nothing but their own info boxes etc.
No search results, nothing external.
That way, anyone looking for any other results HAS to leave Google in order to find anything.
And Google can pander to the percentage of people who honestly don't know or care that there's a web.
Are there enough of us who would avoid Google if we knew 100% that we would never see a reference to anywhere outside of their own properties?
