I put this suggestion in a feedback message but I thought I would post it here as well.
I am totally confused. May I make a suggestion? Perhaps on your About page you could say what DDG actually does. Maybe you could say you are a search engine and where you get your search results data. Is it from your own web crawler or what? The About page seems to start in the middle rather than at the beginning.
An example is that I searched for the "Download Helper" application and got only one result and that was completely unrelated, as opposed to the hundreds of results from other search engines. Do other people get the same results? This happens a lot with DDG so I am thinking I am doing something wrong. So there is another suggestion for your About page: what should the user do and what results should he or she expect?
Last thing: are there issues if you use add-ons such as Ghostery? Shouldn't this be stated on the About page as well?
