I didn't know about it :D
What is it? An alternative to discourse? Maybe GitHub is thinking of integrating forums for the open source projects?
I was thinking the same, lots of people have gitter.im communities for their projects but I guess this cuts out the middleman.
GitHub used to have private messaging between users but it removed it because of the usual reasons. Maybe a zero effort forum tab where users can discuss trivia, features and issues, all out in the open, before actually opening pull requests or asking for bug fixes could be nice.
