Interesting - and nice to see such an early release.
Personally I'm just waiting for the C++/DirectX model to be supported. It makes more sense, because AdDuplex is IMHO best for indie game devs as a hardcoded fall-back position for Microsoft's own advertising platform (which can frequently fail to serve ads, for whatever reason).
A large part of HN is developers trying to make money/earn reputation. An ad network for a new release of an OS is important in that regard. Not a big surprise it's popular.
