Comeone harry, of course there's relevance in comparing people who desire a structured methodical climbing community that requires $ and time to a ragtag website that requires 15 seconds to register.
Perhaps a better comparison, then, would be between the climbing community as a whole and the Mountaineers.
I think climbers that post on cc.com are more diverse as far as ability and preferred types of climbing than Mountaineers. "[P]eople who waste time on cc.com" are such a cross-section of the climbing community, that I don't see any real relevance to such a question. I guess that's what Dru was trying to point out when he said that cc.com posters includes Mountaineers.
You are all referring to cc.com as if it is a community or a club or something like the mounties. Its a frigging website. Its not like people list it in their affiliations in the AAJ, like the AAC or the KTK.
