I've not heard of duckduckgo really but I definitely guess that with all the censorship going round many people are beginning to abandon all this Centralised platform. I guess it's becoming too much.
Basically I think duckduckgo has got a brilliant interphase, I want to ask those it has those incessant ads or are you somehow blocking them really? I basically don't know why Google seems to be thinning their search suggestion I even once heard they removed the word God From their suggestions for search.
