I wish them luck. More competition in search is welcome. I don't think I will use it very often though because accuracy in search results trumps any concern I have with privacy online that I get from using google or bing.
I feel it's somewhat impossible to discern accuracy in search results, as you can't see what's missing. But by the time you feel the results are missing something, they're likely missing ALOT.
As someone who is trying to switch to DDG for the 10th time, I really wish I felt this way. My experience is so different. Right now I’m at the “g! Everything” stage. Which comes right before the “give up and just switch back to google” stage. DDG results are seriously so bad. It baffles me.
I really want to remove google completely from my life. Search and YouTube are the only two things holding me back. And neither have any competition that is even remotely close imo.
