taste

it seems like a big part of reaching an underground audience is taste and acceptance and these two consistently come into conflict for me. how do i promote quality and good art (whatever the hell that means) and giving people a venue to express what they create while still maintaining an end product that has artistic integrity? i know acceptance is a key to community that i suck at embracing (because at the heart i'm egotistical and elitist, but working on it) and i also get positive feebdack from people expressing an appreciation of a quality element in what i'm responsible for(not always done by me, but goes through my filter) so how then do i practice being in community with others who are learning, appreciate them for who they are and what they produce, and still tell them with love and honesty that they aren't ready for the main event? then once that hurdles overcome how do i, we, whoever, help people to improve artistically and what does that mean?
