Exactly! We, the community members, need to keep talking about quality and what that means for us. The rewards system might be AnCap in its operation but it is not the only measure of value and influence on Steem. Money/STEEM is never meant to be a measure of all value ever and so our conversations really do matter. They inform the creators how their creations will be valued.
Though, I would say that any discussion on quality is not separable from a discussion on culture and that culture's embedded values.
I tend to swing towards live-and-let-live pluralism. And this means I support different communities having their own mutually incompatible versions of quality provided they don't impose their hegemonies on anybody else. Cyberspace has infinite room for them all.
