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: 
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.
Here is my two cents. Magento 2 is the newest edition of Magento. If a question clearly states it is related to Magento 2 I see absolutely no reason why it does not belong on magento.stackexchange.com.
