The "Download Code" button just downloads a .tar.gz of code? Doesn't link to the GitHub repo? I mean, either actually describe what 'code' is in this sense (it's a short, simple PHP script, for the curious) or link to the repository. The page itself is hopelessly broad and altruistic without giving any details of the solution, and I'm pretty unimpressed with this code if it aims to be anything more than a proof of concept.
