Before you try to differentiate yourself with new/niche features, you should make sure you're bringing table stakes. The biggest thing stopping me from using DDG is, sorry, the shittiness of the search results. Often I try 3-4 different queries on DDG before giving up and trying my original query on Google and getting the answer in the first result. If there were a "Google with privacy" I'd switch instantly. But right now DDG is "Google with privacy, plus every other search fails".
