 - Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
 - Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
 - We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behavior; we strive to be inclusive. In particular, we don't tolerate behavior that excludes people in socially marginalized groups.
