I agree that reddit, twitter and facebook can’t replace this forum in any way.
Maybe PeerApps will do some wonder!
Meanwhile https://gitter.im/NuNetwork/Nu can be used as chat platform and gists on github can fill the gap for motions and grants.
If https://gitter.im/NuNetwork/Nu gets congested by chatting about different things, additional chat rooms can be created per topic.
The benefit of gitter.im is that there is some control over the participants.
Another fallback is using the Nu board on Peercointalk https://www.peercointalk.org/index.php?board=69.0 for discussion.
Soon there might be a Blocks & Chains Exchange related forum - maybe on a different server?
Having another forum on a different server would make the cooperation with Nu more difficult, though…
The thing is: how do you tell people where to go, if the place where you could tell them is not available?
