I think this was the hardest part for me to learn: the site cares a lot about what I would describe as "tone," which is generally a good heuristic for interesting and productive discussions (but this can feel stifling for a lot of people, particularly but not exclusively minority groups in tech). Early on I definitely engaged in a manner that was less than pleasant, and the culture here seems to take a dim view of that no matter who it's coming from, which is the part I find the most impressive. I have since learned how to say what I want to say without just blowing raspberries (for the most part) and I am generally rewarded for it with interesting comments and upvotes.
