No I haven't read his book, but I know Scott, he's a nice man.
I think that the frustration that you feel is down to the fact that many people of your age (I am assuming you are sort of my parents' age) built the folk scene as it is as young, vibrant poeple, and therefore find it hard to accept that thing you love changing. And I don't blame you, I imagine I would feel the same way. It isn't that nobody appreciates you, it's just that we come from the priveleged position of having most of the hard graft already done and a scene at our disposal-so we will try to improve it on our own terms to express our own excitement, try to expand it to include our friends and peers just as you did. My Mum finds the folk scene bewildering these days, and has as little to do with it as she can. She still loves the music and the ethos though, it's just too commercial for her I think.
