That just raises the question: To what extend does DuckDuckGo still depend on Bing?
I've asked before, and no one seems to be able to provide me with a source that states that DuckDuckGo is just Bing. Yet it comes up every time DuckDuckGo is mentioned in a positive light.
Does anyone outside the company know how DDG works? IIRC a job description hinted at their backend being in Perl, but little else has trickled out. It's easier to find out how Google works, through patents, presentations, the Percolator paper, etc.
Saying that Bing is one of hundreds of sources is like saying that PageRank was just one of Google's 200 signals. Or that Google was just one of hundreds during Bing's hiybbprqag brouhaha.
