I've tried so many times to make DDG work. In fact I'm currently commenting via Android DDG browser and still I find myself switching to Chrome/Google more than half of the time because the DDG search is just not working for me. I suspect the problem is I do a lot of geospatial type searches.
I understand why the results are worse but that doesn't really matter to the general populace.
I wish them the best though. We need search market fragmentation.
