how would you define the success of reddit's comment threading functionality?

Introduction

Defining the success of Reddit's comment threading functionality is crucial for understanding user engagement and the platform's overall health. To approach this product success metric problem effectively, I'll follow a structured framework that covers core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context

Reddit's comment threading functionality is a core feature that allows users to engage in nested discussions under posts. It enables users to reply directly to specific comments, creating branched conversations that can be expanded or collapsed.

Key stakeholders include:

• Users (both commenters and readers)
• Content creators (posters)
• Moderators
• Advertisers
• Reddit's product and engineering teams

User flow:

1. User views a post
2. Scrolls through comments or expands collapsed threads
3. Chooses to reply to a specific comment or start a new top-level comment
4. Submits comment and can further engage in nested replies

This functionality is central to Reddit's strategy of fostering community discussions and user-generated content. Compared to competitors like Twitter or Facebook, Reddit's threading system allows for more in-depth, organized conversations.

Product Lifecycle Stage: Mature, but continually evolving with new features like "Sort by Controversial" or "Collapse All."

Software-specific context:

• Platform: Web and mobile apps
• Integration points: Voting system, user profiles, moderation tools
• Deployment model: Continuous integration/continuous deployment (CI/CD)
