Quora is another good example, it’s a place I often visit after search results, but on google.dk, it’s almost never a result, possibly because it’s not in danish.
DDG is much better, but once in a while when I’m searching for something very specific that I know google will first, I’ll do the !g.
If I’m looking up anything technical or comitting an act of google programming, I’ll always go straight to google.
The other day I was looking for some pipeextenders for our shower though, and neither bing, google or DDG were able to help. I ended up finding them by searching on amazon. Google was 100% commercials for plumbers and completely useless otherwise. DDG and bing had no clue what I was looking for. A few years ago, google would have been able to help, I know, because google helped me find our current ones.
