"But it makes me wonder whether people who say things like that present anything to an audience themselves, and what they hope for when they do. Would they share a photo hoping people would tell them how ugly they are? Surely most of us share what we share because it brings us some kind of pleasure, and we want to share that pleasure with others. Hearing that they enjoyed it makes us feel that what we've done is worthwhile, and motivates us to continue doing it. Hearing that people like something about us helps us feel better about ourselves, allowing us to get through the days without slumping into deep despair. Obviously not all feedback can be wholly positive, but criticism is an unfortunate part of the sharing process rather than a desirable thing."

I'm quite different: I don't expect feedback (nor want it) in the form of encouragement for what I've accomplished. I believe this is called introversion? I just hope what I'm doing inspires someone else to do something at least a little bit similar. Similarly when I give feedback, especially in the past I would be honest and objective and focus on what could be improved, and a lot of people would think I was being mean because of the expectations not coinciding.
