Behind the product: Duolingo streaks | Jackson Shuttleworth (Group PM, Retention Team)

章节 1：播客开篇与访谈背景——为何深究 Duolingo 的连胜机制

📝 本节摘要：

本章涵盖了节目的精彩预告片段与正式开场。Duolingo 的产品经理 Jackson Shuttleworth 首先抛出核心数据：连胜机制（Streak）是公司最大的增长杠杆，目前有超过 900 万用户拥有超过一年的连胜记录。

主持人 Lenny 随后介绍了本期节目的独特之处——这将是一次前所未有的尝试，全集时长将完全聚焦于探讨“连胜”这单一功能的生与死。他指出 Duolingo 近期市值翻倍至 140 亿美元，该功能功不可没。最后，Jackson 正式登场，双方以“老听众，初次连线”的幽默寒暄开启了这场关于“经验富矿”的对话。

[原文] [Jackson Shuttleworth (Teaser)]: ... Duolingo is a $14 billion company, it's hitting all-time highs too, it just keeps going up, but I think it doubled in value in the past six months.

[译文] [Jackson Shuttleworth (预告片)]: ……Duolingo（多邻国）是一家市值 140 亿美元的公司，它正创下历史新高，而且还在持续上涨，我想在过去六个月里它的市值翻了一番。

[原文] [Jackson Shuttleworth (Teaser)]: Streaks is the most impactful feature. We have, right now, over 9 million users with a year plus streak.

[译文] [Jackson Shuttleworth (预告片)]: 连胜（Streaks）是最具影响力的功能。此时此刻，我们拥有超过 900 万名连胜记录在一年以上的用户。

[原文] [Jackson Shuttleworth (Teaser)]: If you look at the numbers, I think it's been our biggest growth lever. What Duolingo really focuses on is, how do we help users build habits around language learning? Getting user come back the next day is the biggest problem to solve.

[译文] [Jackson Shuttleworth (预告片)]: 如果你看这些数据，我认为它是我们要最大的增长杠杆。Duolingo 真正关注的是，我们如何帮助用户围绕语言学习建立习惯？让用户第二天回来（继续使用）是需要解决的最大问题。

[原文] [Lenny (Teaser)]: Let's get into the motherload of learnings from the journey of streaks, talk about the key lessons, insights, and also wrong turns along the way.

[译文] [Lenny (预告片)]: 让我们深入挖掘关于连胜机制（streaks）发展历程中的“经验富矿”，谈谈关键的教训、见解，以及沿途走过的弯路。

[原文] [Jackson Shuttleworth (Teaser)]: I'd say test everything, we've run in the last four years over 600 experiments on the streaks, so every other day.

[译文] [Jackson Shuttleworth (预告片)]: 我会说要测试一切，在过去四年里，我们在连胜功能上运行了超过 600 次实验，几乎每隔一天就有一次。

[原文] [Jackson Shuttleworth (Teaser)]: We've actually set up really good infrastructure for copy testing. We used to say continue, our standard CTA is continue, and we changed that to commit to my goal, and it was a massive win.

[译文] [Jackson Shuttleworth (预告片)]: 我们实际上为文案测试建立了非常好的基础设施。我们过去常说“继续（continue）”，我们的标准行动号召（CTA）是“继续”，后来我们将其改为“承诺我的目标（commit to my goal）”，这带来了一次巨大的胜利。

[原文] [Jackson Shuttleworth (Teaser)]: There's so much human psychology that you all learn through all these experiments of just how to motivate people, what motivates, what demotivates.

[译文] [Jackson Shuttleworth (预告片)]: 通过所有这些实验，你们会学到很多人类心理学的知识，关于如何激励人们，什么能产生激励，什么会产生阻碍。

[原文] [Jackson Shuttleworth (Teaser)]: Say that you played a mobile game, or that you've done it for 3,000 days in a row, I don't know, maybe that hits a little bit different than you've learned Spanish for 3,000 days in a row.

[译文] [Jackson Shuttleworth (预告片)]: 比如说你玩一款手游，或者你连续玩了 3000 天，我不知道，但这可能和你连续学习西班牙语 3000 天给人的感觉还是有点不同的。

[原文] [Lenny (Host)]: Today, my guest is Jackson Shuttleworth. Jackson is a group product manager at Duolingo, leading the retention team.

[译文] [Lenny (主持人)]: 今天，我的嘉宾是 Jackson Shuttleworth。Jackson 是 Duolingo 的集团产品经理，领导留存团队。

[原文] [Lenny (Host)]: This is a different kind of episode that I'm experimenting with, where we spent the entire conversation focused on the journey and lessons of a single feature, in this case, Duolingo streaks.

[译文] [Lenny (主持人)]: 这是一期与众不同的节目，我正在尝试一种新的形式，我们将整个对话都集中在单一功能的发展历程和经验教训上，在本期案例中，就是 Duolingo 的连胜（streaks）功能。

[原文] [Lenny (Host)]: Duolingo is a $14 billion business, just over the past six months, they doubled in value, they're hitting all time highs in usage and market cap, they're also one of the very few successful and also the single biggest consumer app business in the world.

[译文] [Lenny (主持人)]: Duolingo 是一家价值 140 亿美元的企业，仅在过去六个月里，它们的市值就翻了一番，它们在用户使用量和市值上都创下了历史新高，它们也是世界上为数不多的成功案例之一，也是最大的单一消费者应用（consumer app）企业。

[原文] [Lenny (Host)]: And as you'll hear from Jackson, the streaks feature is the single most impactful feature that most contributed to this growth and success. In other words, you could argue this one feature created billions of dollars of value, which to me means it is worth studying in depth.

[译文] [Lenny (主持人)]: 正如你们将从 Jackson 那里听到的，连胜功能是对这种增长和成功贡献最大的单一最具影响力的功能。换句话说，你可以认为这一个功能创造了数十亿美元的价值，这对我来说意味着它值得深入研究。

[原文] [Lenny (Host)]: In our conversation, Jackson shares the history of the streaks feature, all of the biggest wins and wrong turns they've taken along the way, what he and his team have learned about what works and doesn't work with a streaks mechanic, and also how they set up their teams to operate in a way that allows them to run over 600 experiments on this product and continue to find big wins.

[译文] [Lenny (主持人)]: 在我们的对话中，Jackson 分享了连胜功能的历史，他们一路走来取得的所有最大胜利和走过的弯路，他和他的团队学到的关于连胜机制中哪些有效、哪些无效的经验，以及他们如何组建团队并以某种方式运作，从而允许他们在这个产品上运行超过 600 次实验并持续发现巨大的胜利。

[原文] [Lenny (Host)]: I hope to do more episodes like this on features and products that you'd love to hear more about, so leave a comment either on YouTube or on Substack, and tell me which product or feature you'd love to see me cover.

[译文] [Lenny (主持人)]: 我希望针对大家想深入了解的功能和产品做更多这样的节目，所以请在 YouTube 或 Substack 上留言，告诉我你们想看我报道哪个产品或功能。

[译文] [Lenny (主持人)]: 如果你喜欢这个播客，别忘了在你最喜欢的播客应用或 YouTube 上订阅和关注它，这是避免错过未来剧集的最好方法，而且这对播客的帮助巨大。

[原文] [Lenny (Host)]: With that, I bring you Jackson Shuttleworth. Jackson, thank you so much for being here and welcome to the podcast.

[译文] [Lenny (主持人)]: 话不多说，有请 Jackson Shuttleworth。Jackson，非常感谢你的到来，欢迎来到播客。

[原文] [Jackson Shuttleworth]: Yeah, thank you. Long time listener, first time caller. I appreciate it.

[译文] [Jackson Shuttleworth]: 是的，谢谢你。老听众，第一次连线（First time caller）。我很感激。

[原文] [Lenny]: So, this is going to be a really interesting conversation, I've never done an episode like this before, where we basically spent an hour, an hour and a half going into one feature of one product, but this is a very special feature, it's a very special product.

[译文] [Lenny]: 这将是一次非常有趣的对话，我以前从未做过这样的节目，我们基本上要花一个小时、一个半小时来深入探讨一个产品的这一个功能，但这确实是一个非常特殊的功能，这是一款非常特殊的产品。

[原文] [Lenny]: Have you ever spent an hour, an hour and a half just talking about this one feature with anyone?

[译文] [Lenny]: 你有没有和任何人花一个小时、一个半小时只谈论这一个功能？

[原文] [Jackson Shuttleworth]: Well, internally, so when we onboard new folks to the team, we'll do, I actually just did this with somebody that joined the team recently, where we spent, yeah, I was like, hey, let's spend an hour just talking about the streak.

[译文] [Jackson Shuttleworth]: 嗯，在内部会有，当我们为团队新成员进行入职培训时我们会这么做，我实际上刚和最近加入团队的人做过这个，我们花了时间，是的，我就像是在说，嘿，让我们花一个小时只谈谈连胜机制。

[原文] [Jackson Shuttleworth]: We got through an hour and I got through about 30% of what I wanted to share, there's just so much, we'll talk about this, but there's so much that we've learned over the years, but never anything externally like this.

[译文] [Jackson Shuttleworth]: 我们聊了一个小时，我大概只讲了我想分享内容的 30%，因为内容实在太多了，我们会聊到这些的，但这些年我们学到了太多东西，不过对外从来没有像这样（深入分享过）。

[原文] [Jackson Shuttleworth]: I think we've shared bits and pieces of learnings, but this will be the motherload of learnings hopefully-

[译文] [Jackson Shuttleworth]: 我想我们分享过零星的经验，但这一次希望能成为经验教训的“富矿（motherload）”……

[原文] [Lenny]: Here we go. ... of how Duolingo built the streak. We should title this the Motherload of Learnings of Duolingo Streaks.

[译文] [Lenny]: 我们开始吧。……关于 Duolingo 如何构建连胜机制。我们应该把这一期标题定为《Duolingo 连胜机制的经验富矿》。
