Since this platform is part of Microsoft Docs, full integration with Microsoft Docs would be very valuable. As we know, it is possible to add comment and edit documents in Microsoft Docs, but the problem is it required GitHub account and GitHub doesn't support Microsoft Account (you need to create new GitHub account), so I would recommend:
1) GitHub integrate with Microsoft Account , so we could directly sign in to GitHub using Microsoft Account without creating new GitHub account.
2) The account should also integrate with Microsoft QnA to trace activities in GitHub document associated with Microsoft Docs. In this case , it only traces activities on Microsoft Docs in the GitHub.
3) Consider add metrics and contributions in Microsoft Docs in this account.
This would be very valuable because currently users need to setup GitHub account and there is no integrity to trace their activities in Microsoft Docs using GitHub.
