Hacker News 的这份 Guidelines 太棒了，一些 tips 很值得社区经营者借鉴。比如：

• On-Topic: Anything that good hackers would find interesting. Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon.

• don't do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is.

• if the title contains a gratuitous number or number + adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X,"

• Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

• When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."

• Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.

• 主题相关：任何优秀黑客可能会感兴趣的内容。非主题相关：大多数关于政治、犯罪、体育或名人的故事，除非它们是某些有趣新现象的证据。

• 不要做让标题显眼的事情，比如使用大写字母或感叹号，或者夸赞文章有多好。

• 如果标题包含无意义的数字或数字+形容词，我们希望您能将其裁剪。例如，将“10 Ways To Do X”翻译为“How To Do X”。

• 随着话题越来越具有争议性，评论应该更加深思熟虑和有实质内容，而不是更少。

• 当不同意时，请回复论点而不是叫名字。“那太愚蠢了；1 + 1 等于 2，不等于 3”可以简化为“1 + 1 等于 2，不等于 3。”

• 请不要发布肤浅的否定，尤其是针对他人工作的。好的批评性评论能让我们学到一些东西。
