Call me old fashioned, but I think there have been times that I resorted back to Google just because it's easier to type than DuckDuckGo (Bing is even easier).
For all the hate Google receives, I think at least their search engine "name" is not as poor of a choice as DuckDuckGo.
Edit 1: I know you can add DDG as a search engine in your browser, and I know that you can assign shortcuts to it. But I'm afraid, that's not what 99% of people would do. The name is just weird, hard to type, and long.
Edit 2: If you Google DDG, it'll show the American rapper instead of DuckDuckGo. They could've come up with a name that's not already popular.
In Chrome settings I set DDG as the default search engine and it's just _there_. Don't have to type anything. In Firefox settings just set your homepage to DDG.
People are switching to DDG from word of mouth.
