This comment doesn't correspond with the content of the blog post. It relates to Google's algorithms; one's personal choice of search engine does not change the fact that the results Google shows are ultimately seen by more eyes than anything else.

I still can't see the link to individuals using DDG as an immediate or relevant solution to the problem discussed by the author. The comment, to my eyes, came off as flippant.
