I used to frequent rec.music.folk decades ago when it was a thriving Usenet News group. I haven't thought about it for a long time but have just looked it up. Seems it's a discussion group on Google now with about three threads per month and most of the postings done by a person who seems to be completely bonkers. E.g. he claims to be a "matchmaker" and discusses the sexual compatibility of certain musical and political celebrities. Just keep away from that.
