I moved to DDG a few years back and don't miss Google. While it is possible that Google might have provided similar results to what DDG did for the same query, I have noticed that when DDG fails to provide good results, Google fails with it. And the author is right about appending the site name to the query (reddit etc). Sometimes, it is the only way to avoid the crap that the search engine would otherwise provide.
Sure, but just lately DDG started deteriorating for me as well. Maybe that coincides with another big update they did and didn't tell anyone about it -- looking for certain phrases that describe sex no longer works. A lesbian friend made me aware of that; she recently complained that she can no longer find porn through DDG queries so she started bookmarking various such websites and is going to them directly. ...What…
I don't get the hype around DDG. They are at the mercy of the underlying search engines.
