I'm asking because adding the "!g" takes about 6-7 screen touches so it's quite inefficient, and it basically keeps me from using DDG.
PS uh, rather the whole page is related to dart.
I do prefer not leaving all my data with Google though to combine with other activities of which I may or may not know of and I think it's good to use alternative services as much as possible, especially when I use Google just as an interface to surface information from site like Wikipedia or Stackexchange.
(note I'm not affiliated with DDG, I just also went through the process of De-Googling after Inbox was shut down)
Also google having more results you are looking for sometimes doesn't mean you can't have DDG as your default search. Just enter 'dartlang !g' when you want to search google.
