I was referring to the hackers who use the forum, not the ones who run it. Sorry for the confusion.
It really is much easier and more beneficial for everyone to just be nice. Why work harder to achieve less?
A few strategies that have made it easier for me to "be nice":
1. Avoid long back and forth threads. Say what you have to say and get back to work.
2. Try to plan your comment to not be misinterpreted. This avoids much unnecessary pain. It's also difficult.
3. If someone responds negatively to you, wait and let others respond on your behalf. It's amazing how much better this feels.
4. Imagine that the other person has 42 legitimate reasons for not being nice. Let 'em slide.
5. Imagine that the other person may someday be your ideal co-founder, mentor, collaborator, customer, or angel. (Or more likely, your ideal co-founder, mentor, collaborator, customer, or angel is witnessing this exchange.) Don't say anything to scare them away.
6. Most of all: It doesn't matter! This is all optional. We were all busy working before Hacker News and will be busy working after Hacker News is gone (perish the thought). Lighten up.
