Be Kind
I really like these two paragraphs towards the end:    Being kind isn’t the same as being nice. It isn’t about superficial praise. 
    It doesn’t mean dulling your opinions. And it shouldn’t diminish the passion 
    with which you present them.
    
    Being kind is fundamentally about taking responsibility for your impact on 
    the people around you. It requires you be mindful of their feelings and 
    considerate of the way your presence affects them.

This get's missed a lot here on Hacker News. Many people are often hostile towards content creators or other commenters.It's perfectly OK to disagree with someone; but please consider doing so in a respectful and thoughtful tone. Remember that others often shut-down when they read criticism, even when well warranted. The way you phrase and present yourself defines whether you're giving criticism or critique.
