"Denigrating art you don't understand doesn't hurt the art--it reveals something about your willingness to learn."
"When (part of) your marketplace embraces a 'new' that makes no sense to you, it's essential you understand the point of view that's leading people to embrace this new idea. No, you don't have to cheer it on, collect it, support it or pretend you think it's the greatest breakthrough ever. But yes, you probably need to understand why other people were touched, inspired or found something worth talking about."
Both quotes were taken from this Seth's Blog post.
