I'm in eighth grade right now. For a class persuasive speech, I chose to talk about why DuckDuckGo is better than Google. (i.e. Google's Filter Bubble, The NSA Surveillance Issue, etc.) Donttrack.us and Dontbubble.us were very helpful.
And after a three-minute speech, I'm pleased to report four of my fellow classmates are now using DuckDuckGo!
(I even had a sign that I used during the speech!)
