I think the answer lays in getting "new blood" into the scene. Folk is a wide genre, some would say it is a 'roots' scene, young people have to be attracted, and Folk (or F**k as I call it,) must be re-popularized as per the 60's (Dylan, Donovan, Peter Paul and Mary, etc) . Also, here's a poser: Why does Vin G not take one of the opportunities which must surely come his way, to go on TV? this would surely be a start.
Festivals? Mini Fests, short things for those of the generation with a 'short little span of attention' (spot the lyric). Folk on Dude!
