I agree to a point input is the only way to improve brewing. Yours mine and others. Judges have to go through classes and multiple testing and tastings. Now granted everyone's taste buds are different but still valid to get as much information as possible on your beer. If someone tasting my beer if there is something about it they don't like I'm interested if they have something to help improve not just a "This tastes funny" comment.
I get what you're saying, but I'm brewing to my tastes, just like any other home brewer should. I could brew a classic style (seems to be what the judges want) to perfection, but if I'm not satisfied with it, what's the point?
