channels

If channels were free to create (and burn when dead) what kind of opportunities would open up for communities? 
One of the biggest concerns I hear from people using this platform for collaboration is inability to organize conversations effectively. 
I think channels is the way to go on this, as long as they can be removed from the UI when the usefulness of the convo ends. But it has to be free to make channels to do this. Let’s face it, Discord still rules as far as a community organizing tool goes and a large part of it is because you can create “channels” at will.
