> One, we become focused on the negative, so we train ourselves to see flaws. This focuses us to be negative by a fault, and we see this online when say, there’s a post about a cool article. The first comment will be a criticism of a minor point wrong in the article, and then there will be chains of comments criticizing the criticism. It’s like nobody even read the article. This also leads to a lack of appreciation and gratitude where nobody says “that was a really great idea”, “I like that they said this…” or “thanks for sharing!”. I believe there was a rule in HN guidelines about posting simple "Thanks" or "me too" comments, but I can no longer find it. Maybe we truly spontaneously train ourselves to not post such comments. On the other side, a long stream of "Thanks for sharing" comments without any more substance is pretty boring.
