Question: I certainly don't think inquiries about Magento 2 belong in the magento.stackexchange; can we hurry up and confirm/enforce this? I feel all inquiries should be directed at the brand and/or the repository.

Answer: 
Magento 2 questions are allowed.  

They should just be tagged with the proper version to make a difference between pre-alpha, alpha, beta, rc and official release.
I think some question which fit squarely into the "issues" bucket *belong* on GitHub. But for questions which do not rise to the level of "hey something's broken" or "hey I have an architectural suggestion / improvement" are noise in a GitHub context. My opinion of course, and curious to hear the opinions of others.
