不要把时间浪费在那些讨论门槛低、谁都能发表看法、很难达成共识的话题上，比如自行车棚的颜色。

Thus, consensus is hardest to achieve in technical questions that are simple to understand and easy to have an opinion about, and in "soft" topics such as organization, publicity, funding, etc. People can participate in those arguments forever, because there are no qualifications necessary for doing so, no clear ways to decide (even afterward) if a decision was right or wrong, and because simply outwaiting other discussants is sometimes a successful tactic.

因此，在技术性问题中，那些易于理解且容易产生看法的问题上，最难达成共识。而在诸如组织、宣传、资金等“软”话题上也是如此。人们可以永远参与这些争论，因为无需任何资格即可参与，也没有明确的方法来决定（即使在事后）一个决定是对是错，而且有时仅仅是比其他讨论者更有耐心等待也是一种成功的策略。
