Lessons from Adam Mosseri

Adam Mosseri runs Instagram and previously led Facebook's News Feed. He oversaw the app's shift from chronological photos to an algorithmic platform focused on video and direct messaging. This collection gathers his statements on product strategy, the creator economy, and the mechanics of running social networks at scale.

Part 1: Product Strategy and the Algorithm

  1. On Multiple Algorithms: "Instagram doesn't have one algorithm that oversees what people do and don't see on the app. We use a variety of algorithms, classifiers, and processes, each with its own purpose." — Source: [Glasp]
  2. On Chronological Feeds: As the number of friends and accounts people follow grew, chronological feeds became impossible to manage, causing people to miss the vast majority of posts from their connections. — Source: [Business Insider]
  3. On the Most Important Metric: "If you're trying to evaluate how your content is doing on Instagram, I would look at sends per reach. Of the people who saw it, how many of them sent it to a friend?" — Source: [Substack]
  4. On User Agency: "I believe it's in our best interest as a business to empower people to shape Instagram into something that works for them, and that people should be able to have a meaningful amount of agency." — Source: [Engadget]
  5. On the Feed's Evolution: Because personal moments largely moved to Stories and direct messages, public feed posts became less frequent, and algorithmic recommendations filled that gap. — Source: [Engadget]
  6. On Ranking Signals: Feed ranking relies on a user's history of interactions, which heavily weights likes, comments, shares, and saves. — Source: [Hypebeast]
  7. On Transparency: "It's hard to trust what you don't understand. We want to do a better job of explaining how Instagram works." — Source: [Business Today]
  8. On Deprioritizing Spam: During his time leading the Facebook News Feed, the focus was to reduce the influence of spammers and deprioritize the links they shared more frequently than regular users. — Source: [Wersm]
  9. On Feature Complexity: A persistent tension in platform development is that the product can often feel too complicated, making it a challenge to evolve without sacrificing usability. — Source: Lenny's Podcast
  10. On Product Adaptation: Part of the company DNA is competitiveness and the willingness to adopt and refine formats that become industry standards if they serve the user. — Source: [Business Insider]

Part 2: The Creator Economy and Monetization

  1. On Creator Success: A primary lens for evaluating new features is their ability to help creators thrive, gain reach, and maintain a sustainable career. — Source: [Deciphr]
  2. On Replacement Value: "Let's say you made 10 Reels through the program, and they all got really good views. But if you hadn't made them, we would've had just as much engagement from content that wasn't paid for... the ROI is negative 100%." — Source: [TubeFilter]
  3. On Small Creators: "The vast majority of creators are very small, and they're too small to monetize in a meaningful way... it's actually not the thing they can or should really focus on." — Source: [TubeFilter]
  4. On Reach as a Tool: "Reach is a means to an end, not an end in and of itself." — Source: [Buzz In Content]
  5. On the Creator Funnel: When launching new platforms, bringing creators on board early creates a fear of missing out that drives broader user adoption. — Source: [Deciphr]
  6. On Listening to Creators: The platform's direction is heavily influenced by feedback from creators who depend on the app for their livelihood. — Source: [Substack]
  7. On Content Strategy: "Don't force it as a creator, but if you can... think about making content that people would want to send to a friend, to someone that they care about, and it will help your reach over time." — Source: [Purdue University]
  8. On the Limits of Revenue Share: Direct revenue-share models do not apply cleanly to all formats, particularly fast-scrolling short-form video where determining exact attribution is difficult. — Source: [Passionfruit]
  9. On Building for the Creator Class: Instagram transitioned from a chronological app for friends to a platform fundamentally structured around the broader creator economy. — Source: [Minter.io]

Part 3: Content Shifts and Video

  1. On the Square Photo Feed: "Unless you are under 25, you probably think of Instagram as a feed of square photos... That feed is dead. People stopped sharing personal moments to feed years ago." — Source: [Economic Times]
  2. On Polished Aesthetics: The platform has shifted away from the era of high-contrast photography, skin smoothing, and perfect landscapes. — Source: [The Hindu]
  3. On the Shift to Video: The amount of content people post publicly in feeds is dropping because users are moving their attention toward Stories and video formats. — Source: [Business Insider]
  4. On the Panavision Mistake: In 2021, the app introduced too many major changes at once by pushing video and recommended content too fast, which alienated core users. — Source: [Podcast Notes]
  5. On the Decline of Public Sharing: Users have fundamentally changed how they share, taking their personal interactions out of public feeds and into direct messages. — Source: [Om.co]
  6. On Stories Adoption: The decision to launch Stories was a direct response to user behavior, specifically the need for ephemeral, low-pressure sharing. — Source: [Business Insider]
  7. On Private Messaging: Younger users increasingly rely on direct messaging because it offers a communicative space completely separate from parents and public scrutiny. — Source: [Podscripts]
  8. On Competing Formats: The distinction between different video products like IGTV and early Reels was too nuanced for the average user, requiring the app to consolidate its video offerings. — Source: [Pocket-lint]

  10. On Learning from Rivals: Successful competition requires the humility to learn from competitors rather than simply assuming your product is superior. — Source: [Podcast Notes]

Part 5: Well-Being and Platform Responsibility

  1. On Addiction Terminology: "I think it's important to differentiate between clinical addiction and problematic use." — Source: [PBS]
  2. On Problematic Use: Problematic social media behavior happens when someone spends more time on a platform than they actually feel good about. — Source: [PBS]
  3. On the Subjectivity of Usage: "Yeah, I do think it's possible to use Instagram more than you feel good about. Too much is relative. It's personal." — Source: [The Statesman]
  4. On Profit vs. Well-Being: "It's not good for the company, over the long run, to make decisions that profit for us but are poor for people's wellbeing." — Source: [PBS]
  5. On Youth Safety: "Keeping young people safe online is not just about one company." — Source: [CBS News]

  5. On Rawness as Proof: "In a world where everything can be perfected, imperfection becomes a signal. Rawness isn't just aesthetic preference anymore—it's proof." — Source: [The Hindu]
  6. On AI-Generated Engagement: The integration of synthetic media forces platforms to rethink how they evaluate content quality when polish is no longer an indicator of human effort. — Source: Colin and Samir
  7. On Labeling AI: Providing users with deeper context about the accounts sharing content is a critical step in helping audiences decide who to trust. — Source: Colin and Samir
  8. On the Devaluation of Polish: A highly produced aesthetic is losing its premium because generative models can replicate perfection effortlessly. — Source: [The Hindu]
  9. On the Future of Identity: The defensive posture for creators moving forward is to embrace flaws, as imperfection is the only thing AI struggles to fake authentically. — Source: [CNET]

Part 7: Threads and Market Competition

  1. On the Standalone App Debate: Launching Threads as a standalone app instead of a feature inside Instagram was a hugely contentious debate internally. — Source: [Business Insider]
  2. On the Risk of New Apps: "A separate app is way less likely to succeed because you have to bootstrap a user base from very little... But if you do it, if you succeed, the upside is so much more significant." — Source: [Business Insider]
  3. On Leveraging the Social Graph: Allowing users to carry over their Instagram social graph lowered the barrier to entry, enabling Threads to reach 100 million users rapidly. — Source: [Inc]
  4. On the Chicken-and-Egg Problem: To solve the cold-start problem for Threads, Meta prioritized onboarding creators first so that general users would have content to consume. — Source: [Deciphr]
  5. On Establishing Tone: Building comment controls and moderation features into a new text app is less about utility and more about setting the cultural tone of the network. — Source: [Platformer]
