I've said this every time the issue has come up: I think the name is hurting, a lot. More than once, I've wanted to just try a quick search on DDG to see it's comparison to Google, and at least some of those times, I've given up because writing duckduckgo is annoying. Is this logical/rational? NO. Is this how I, at least, behave? YES.
And for anyone saying that you can set up your browser to search DDG automatically, that's great if you've already bought into DDG, but it's not something I would do right off the bat.
