I think your moderation has made me better at HN, and consequently I'm better in real life. Actively thinking about how to better communicate and create environments where everyone is getting something positive out of the interaction is something I maybe started at HN, and then took into the real world. I think community has a lot to do with it, like "be the change you want to see".

But to your point, yeah my current company has feedback guidelines that are pretty similar: criticize the work, not the worker, and it super works. You realize that action isn't aligned with who you want to be or think you are, and you stop behaving that way. I mean, it's worked on me and I've seen it work on others, for sure.
