While this is certainly an impressive feat, I've not found myself impressed with DuckDuckGo's results. I love the principles of having search results be free of personal information but, for a search provider that essentially collects and organizes other search engine's results, I always find myself back at Google. Often times the result I wanted was as many as 4 or 5 pages back, whereas with Google it's usually in the first 5 or so results, immediately seen on the first page.
