I work at DuckDuckGo. Our most popular open source project is DuckDuckHack: http://duckduckhack.com/ Developers leverage code, APIs, wikis, etc. to answer searches (across a broad range of topics) in few or zero clicks. What we call, "Instant Answers."
The nature of the project only works well with the involvement of non-developers in that the best Instant Answers are made by subject-matter experts across a variety of fields. Suggesting ideas, finding great sources, and the overall experience of the IA are all better if coming from someone who really wants to improve searches for that topic. https://duck.co/help/community/contributing
Let me know if you're interested in getting involved--any time :)
