Some good stuff there - I imagine that is what people who wish the Mudcat would exclude everything that wasn't strictly on topic and to do with folk music would prefer it to be like here. I wouldn't. (Even aside from the fact that the architecture of the Mudcat is so much more user friendly. Well, this user friendly.)

I'd see classical guitar related threads fitting in fine here - I'm sure if he posted any queries or comments he'd be likely to get plenty of knowledgeable responses.

And I think the same would apply to other classical music threads. The Mudcat has stretched pretty far to take in all varieties of popular music, I can't see why it can't do it in another direction if people wish to take it there. After all O'Carolan is a lot closer to other 18th century European composers than he is to Oasis.
