原文来自Benchmark新的合伙人Sara的blog。Sara是Pinterest的第一个投资人，也是后来Pinterest的第一批产品经理，经历了Pinterest发展的各个阶段。她提出产品的成功取决于用户的参与度。用户参与度的等级模型对于理解消费产品最终能走多远有很强的指向意义。原文主要是她发布的PPT，我把PPT翻译成中文。Enjoy！

Almost a year ago, I published a framework I called The Hierarchy of Engagement, that synthesized my thinking on how to build a product that endures.

大约一年前，我发布了这个所谓的用户参与度层级的模型，整合了我关于如何打造一款持久的产品的思考。

Since then, I’ve had countless conversations with founders about the hierarchy and how it impacts their product roadmaps. And over the past year, each time I presented it, I found myself tweaking, clarifying, adding layers.

从那以后，我和很多创始人无数次讨论这个层次结构，以及对他们产品路线的影响。过去一年里，atv，每次我展示它，直播， 我发现我不断的完善、澄清和增加内容。

The presentation is still mostly the same, but there are enough differences I figured it was worth publishing the expanded version, pasted below. As always, please let me know if you have any feedback or questions.

演示文件大体上还是一样，但是修改了多处我觉得还是有必要把扩展的版布发布出来。有什么问题，欢迎反馈。
