Not sure this is true. Just yesterday I had to explain to an average user how ddg was answering a query they couldn't get answered in google. This was a really basic thing (finding the NYC office address of a company we were working with). For some reason Google just wouldn't return the result whereas it was top hit on ddg.

My experience is the exact opposite. DDG works well for most things, especially programming, but when I want to find the address of a local business Google is much better, probably because they use my location.
