I'm a listener not a performer, due to a distinct lack of musical talent. I go to folk clubs and join in the chorus songs, I go to concerts at festivals but not to singarounds or (shudder) sessions. I don't folk-dance or dress-up. All of which doesn't place me in one of two mutually-exclusive boxes but does place me at one end of a spectrum.   Yes, I do feel my "kind" is under-represented on Mudcat but don't feel that is either surprising or anything to be worried about. I have been known to speak out if feeling somehow neglected.

My wife was like me but (having rather more musical ability) does go to singarounds, has gone to singing workshops and has turned into a quite acceptable club singer. She's opening for Cloudstreet at the Clarence next month.

My daughter - shock horror gasp! - carries her tankard around at folk festivals.

So where to place them?

I don't see any value in "splitting" folkies into different categories: as the above thread shows they'll only split themselves into different groups that you never thought of in the first place. I certainly don't think that asking questions on Mudcat will help too much in planning for festivals: the Mudcat participants are a sub-group in themselves and not representative.
