Well, I doubt they could throw something this slick together in a copule of weeks! Also, that DuckDuckHack looks to be something very different. I couldn't find anywhere that allows you to sandbox code on it. Seems to need to upload to a github repo first? What actually does it intend to be?
DuckDuckHack is the public contribution part of DuckDuckGo. Most of our Instant Answers are created by developers submitting code to repos on GitHub which we then review and publish. Many of these are programming-related but a bit different to what Bing has announced.
