I know what its like to be on the other side of it too. I've had plenty of things I've done posted to HN over the years. I've gotten all sorts of comments.

Honestly, I'm chuffed and always a little surprised when people read what I've written, or when they like my work. If someone says your software has a bug, that means they liked what you're doing enough that they took time out of their day to try it out. It means they care about the problem you're solving enough that they want you to fix it.

I'd take criticism every day over getting no response at all. Criticism of features means you're solving a problem people care about. If the feature they criticise is obscure, it means all the other features are working better.

I don't know if that point of view is teachable though. Even knowing all that, I feel criticism incredibly acutely in person. Stepping on stage and showing your work to a crowd is terrifying. But I think its good for us. It tempers us, somehow. Makes us more real.
