I have an idea, how about you add a feature, opt-in where you track the searches I do, and then do again with an added !g, at which point, store those in a list where I can go back and add feedback to each one where I got improved google searches, Or the ability to leave up a DDG feedback window when I do those searches. If you make it easy for me to give you feedback, I'll give you limitless amounts of it.
