I'm not going to engage in a long what-is-folk dialogue, I know what I believe it to be and it isn't defined by an historical category but is on-going and adapts to the resources that surround it. With open-mindedness Folk could find a new definition that retains pre-industrial roots and encompasses modern vernacular forms but there's no appetite for it among the orthodoxy so the barrier remains.

'Dilute' seems to be precisely what folkies believe will happen if ordinary people get a say.
