DuckDuckGo added two new content providers to its "zero-click" search results:

Another addition to zero-click is definitions from The Free Dictionary. DuckDuckGo founder Gabriel Weinberg says this greatly expands the number of definitions in DDG's search results.
DuckDuckGo has already been using Wikipedia for similar functionality. Other zero-click additions include emoticon explanations (like this example) and content from 13 additional StackExchange sites.
