I agree this is pretty cool, but the more I search the more I feel that the results are targeted solely towards early adopters. Google is the behemoth that it is because normals mistake it for the very Internet itself. If duck duck go wants a shot at any significant share of the search market they'll have to be more welcoming of those same type of folks.
It's funny, because it's really designed for normals, and the early adopter types complain a lot (rightly so from their perspective) about things for them--bigger text, less density, lighter feel, etc. I do make features for early adopter/advanced users though. It's really a hybrid approach in attempt to "cross the chasm" and get these folks to help introduce it to normals, e.g. their parents and siblings.
