As a person who spends the greater part of his workday conducting online research via search engines, I have tracked Duckduckgo's journey from an okay search engine to the top publicly available search engine. The minimal paid placements and the absence of bias allows me to find the exact information I am looking for without having to scroll to the second or third page - which is currently the case with Google. I do not have the technical knowledge to vouch for the validity of the no-tracking claim, but the simplicity of getting to the information I need without being spoon-fed useless information makes Duckduckgo my search engine of choice.
