I just heard the search engine :) I think most of people still use Google because Google still provide the best result, even now Yahoo! And Bing start grab the Google users. Google try to improve the search result by making agreement with twitter to provide real time story.
Google did this to keep their superiority on search engines business.
Since DuckDuckGo is a new search engine I doubt that very many people have even heard about it. Your question here however may stimulate some interest in it. ;-) So, yes most people use Google as compared to DuckDuckGo.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
