🚀 Deep Dive: How to Build a Truly Engaging Feed Experience – And What It Takes 💡

We’re all chasing that “aha!” moment – that feeling when a product really clicks with a user. But how do you build a feed experience that goes beyond endless scrolling and delivers genuine, deep engagement? That’s exactly what was explored in a fascinating presentation on building a “VD” (Feed Deep Dive) experience, and we’re breaking down the key takeaways for you. Let’s dive in!

🎯 The Challenge: Beyond the Scroll

The initial goal was simple: build a deeply valuable and engaging experience for users, moving beyond the standard feed. The initial assumption? More context is always better. However, the team quickly discovered that nuance is key – the right context is what truly matters. The biggest hurdle? Finding the sweet spot between the quality of responses and latency (speed). Turns out, users who are already deeply engaged are often willing to trade a little latency for a significantly better answer.

🛠️ Key Strategies for Building a Stickier Feed

So, how did they tackle this challenge? Here’s a breakdown of the core strategies and what they learned:

  • 👑 Context is King (But Right Context Reigns Supreme): Understanding which context is most relevant for a user’s query is absolutely critical. It’s not just about throwing everything at the problem; it’s about delivering precisely what’s needed.
  • 🤖 Agentic Models to the Rescue: This was a game-changer. By utilizing agentic models incorporating planning, tool calling, and reflection, the team could dynamically determine which tools and data sources to leverage. This allowed for incredibly fine-grained control over the quality vs. latency trade-off. Think of it as a smart assistant deciding exactly what resources are needed for each request.
  • 🧠 Smart Caching - Freshness Meets Speed: The team implemented a clever caching strategy. Frequently accessed topics like news and sports get shorter Time To Live (TTL) for maximum freshness. Less time-sensitive content, like how-to guides and recipes, can benefit from longer TTLs, boosting speed and efficiency.
  • 👥 Cohort Identification & Targeted Experiences: Not all users are created equal. Identifying and understanding different user cohorts (based on feed usage and VD usage) allows for personalized experiences. The team explored User-to-User (U2U) and User-to-Media (U2M) models to refine targeting and focus on high-value users.
  • 📈 Online Model Improvement with Auto-Judges: Continuous improvement is essential. Auto-judges are employed to constantly monitor response quality and identify areas for enhancement, particularly focusing on reducing “refusals” – situations where VD can’t provide an answer.
  • 🔒 Privacy-Preserving Social AI: A Delicate Balance: There’s huge potential to leverage VD for social use cases, but only if it can be done responsibly. Exploring ways to harness the power of social connections while respecting user privacy is a key priority.

⚙️ Under the Hood: Technical Implementation & Trade-offs

Let’s peek behind the curtain and see how these strategies translate into technical realities:

  • Dynamic Tool Calling & Reflection: Agentic models aren’t static; they dynamically choose which APIs to call based on the specific query.
  • Continuous A/B Testing: The team embraced a culture of experimentation, constantly running online A/B tests to optimize performance and validate hypotheses.
  • Auto-Judges - Your Quality Control Team: These automated systems are the eyes and ears, monitoring response quality and flagging areas needing improvement.
  • Cache Management - The Tightrope Walk: Balancing the need for fresh, up-to-date information with the performance benefits of caching is a constant challenge.

✨ Future Horizons: Expanding Possibilities & Monetization

The journey doesn’t stop here! Here’s a glimpse of what’s on the horizon:

  • Expanding VD’s Reach: Exploring new and innovative applications for VD beyond its current functionality.
  • Contextual Advertising – Seamless and Relevant: Integrating ads in a way that’s both relevant to the user and non-intrusive.
  • Understanding the Social Graph: Leveraging social connections to create an even more personalized and engaging VD experience.

⚖️ Key Trade-offs to Consider

Building a truly engaging feed experience isn’t easy. Here’s a reminder of the critical trade-offs:

  • Quality vs. Latency: How much speed are users willing to sacrifice for a better answer?
  • Freshness vs. Cache Efficiency: Finding the right balance between up-to-date information and fast loading times.
  • Personalization vs. Privacy: Delivering tailored experiences while respecting user privacy concerns.

The presentation underscored that building a deep and engaging feed experience requires a thoughtful approach, a willingness to experiment, and a constant awareness of the trade-offs involved. It’s a journey of continuous learning and refinement – and the rewards are well worth the effort! 🚀
