DDG is excellent for programming questions/how-tos. It shows popular StackOverflow questions inline[1]. For Python, it shows Python/NumPy/SciPy documentation inline as well[2]. It may do this for other languages, but I have not witnessed it.
DDG also has a great inline weather "app" using DarkSky (which is an underrated weather site, IMO)[3]. Searching for businesses/restaurants shows a mini map ala OpenStreetMap (or other providers if you choose) and business information from Yelp[4].
DDG also has a community-driven program to add more search features, called DuckDuckHack[5]. I believe all (at least most) of the features I shared above came through that program. A list of all "Instant Answers" can be found here[6].
Need to fallback to Google? (I personally never have.) There's "bangs" for alternative search engines and popular sites[7].
Make the switch. You'll be pleasantly surprised how easy and refreshing it will be.
