I don't know if this is the right place to talk about this but what I've always really wanted out of Duck Duck Go is "category" filters or maybe even anonymous user profiles. A problem that I have is that most of my queries make sense within a certain domain. Example: I wanted to know about Chicken Scheme. During my exploratory phase, I'd sometimes search for "Chicken Lisp" and would get results for "chicken lips" with a very small font suggestion for refining my queries further. Perhaps, if I was able to select a category (software engineering) it would automatically skew my search results for that preferred domain. Maybe a !cat macro? Google doesn't really have this problem either - and I'm guessing here - because it is either better at guessing intention or because it knows that I'm a software engineer because of my previous searches and then it automatically customizes my search results within a boundary of correctness - i.e, if OhSoHumble searches for chicken thighs then that person probably wants recipes rather than info on a Scheme implementation. I guess account profiles would somewhat help with this as well - where you can opt into skewing your own results on the regular. Regardless, I think there is a good middle ground to take between "collect as much data on this individual as possible to customize their results" and "put programming related search results at the top if the individual asks for it".
