@MattYetAnotherUserName:Handing over Unity was a difficult (and emotional) decision. Many people have been unhappy about it. I know that my sentiments may seem disingenuous, but I am very positive about the new owners.
Regarding GitHub, it won't replace MSDN for us as a publishing channel. Instead, it serves the same role that CodePlex did for us. It's an area where we will be activiely working on content in the public and a point of community collaboration. We intend to publish content on azure.com (instead of MSDN), but that isn't in place yet.
Regarding the multiple places to comment: yes, this is a problem. It's not a new problem though. We've had too many many disparate channels for years. I'm very sensitive to this, but I don't have an answer yet. Today, we are trying to direct everyone to GitHub but I know that's not ideal.
