I was watching the beginning of Bang Bang Con (!!Con) and they talked about their code of conduct. I liked these three tips they gave to stay in line with their values:

• “Avoid feigning surprise.” When someone says something like “I’ve never heard that you can do x,” instead of replying “You’ve never heard that?!” take a moment to revel in the fact the person is about to learn something new and cool. Let that frame your response.
• Avoid “well, actually...” if someone says something not quite correct.
• Avoid subtle -isms like “so easy my grandmother could do it.” That’s a subtle exclusion of women and older people.

Edit: these are based on the Recurse Center’s social rules.
