Hi Vladan,
That's exactly what I'm after. How fine a hair is this 
splitting for the quite possibly disproportionate press it 
gets on list? Where does this practically belong in the action 
function triage hierarchy? Is it fundamental, or incidental-if 
we have the slack to consider it as important esoterica? 
What's the real smoke/flame ratio, or is there one?

Which is why I ask. I'd like to see some real cause and effect 
relationships connecting here, if anyone has information that 
intersects.
