Most of the changes mentioned in [1], don't fundamentally change the experience of using Github. It still is essentially a git repo hosting platform.

Is there anything you would like that can improve the process of collaborating on code (such as an irc like chat integrated into Github)?

Fundamentally, how would you improve the process of collaborating on projects, not being limited to repo hosting?

Do you feel that the developer experience of collaborating on code is broken as there are multiple tools that we have to use such as Github for repo hosting, irc for discussions, mailing lists, audio/video chat when collaborating with a small team?

How can the the developer experience be improved with Github only being a part of the puzzle?
