I find quite like the debianfork website and find it quite appealing myself but it's very clear that it's just a banner page for those who have no understanding of what the fuss is about.
Like wise the #debianfork channel has lots of chatter and bugged by systemd trolls. But they do have a development channel and git repo and plans for a wiki etc. I read a thread about whether they needed a forum or not, it's early days but it looks like it's growing legs and will become a reality. When I first used to visit there was like 35 folks in the channel last time I looked over 170 so it seems to be growing and no doubt will create the infrastructure it needs.
It also looks like it has a "real" name and not debianfork which was chosen when some one was told in the #debian channel to "Why don't you go ask in #debianfork". So #debianfork was created as a channel for open discussion because it was suppressed in #debian! ironic or what. In what looks like a following in the naming tradition the new name seems to be "Devuan" which I guess is a play on Debian and VUA and would in that case be said as "Dev-oo-an" . Anyway if you can ignore the chatter there is very good info in that channel and there seems to be open and honest debates even with the trolls.
edit: Seems my guess was wrong https://devuan.org/
Dear Init-Freedom lovers, the Veteran Unix Admin collective salutes you!
Our project is called "Devuan".
Devuan is spelled in Italian and it is pronounced just like "DevOne" in English.
