Duelling Bouzouki's new venue is an example of the way to go.

Sounds great if you want to pay concert prices to see established acts. (That's not meant sarcastically - it does sound great, and I'd be happy to support a similar venture round here.) But it surely isn't the way to go, unless you wanted to carve the amateurs out of the folk scene completely - and if you did, where would the next lot of professionals come from?
