My guess is they are drawing parallels with it being open to submissions, sharing and reviews(discussion). Prolly not the source control part of it. Though that would be a good feature to have.
That would make almost every website the "Github of X" since submissions, sharing and comments are core features of many websites. Is HN "the github of cynicism"?

I believe yes. You mostly have similar features with different service providers. It's just the differing terminology. Also, once you are done with the certification, you can dive further into current trends in the area of virtualization (for ex. containers)
Totally agree with the post. It's like all data and we need platforms to derive information from the stream. Probably something like http://summly.com/ for your lists?
