For what my opinion is worth, I don't think "taste", good or poor, enters into it. Will Fly above said a lot of what is in my mind about this.
On the contrary, I feel that it is a modern aberration to leave people in isolation from their community in the name of "taste" or "privacy." It's just a symptom of our general alienation, one we shouldn't hold up as normal or desirable. We as a community (define it however you will, but I am sure there is some sort of community bond between us and musicians we admire and identify with despite having never met) need to come together more, not less, and share the common woes and triumphs of our common humanity.
Sure there is a line somewhere that is better not crossed. I can't define it, but like the man said, "I know it when I see it."
Lately at least I haven't seen the line crossed here.
Cheers
