Facebook's growth was initially slow, taking a year to reach a million users, but this time allowed us to refine the product and ensure it met user needs effectively.

Facebook's growth was primarily through word-of-mouth rather than email sharing, as it lacked a native way to contact non-users.

Facebook's decision to not charge users was strategic, allowing them to build a successful ad business based on scale.

When I first met Mark Zuckerberg, I was struck by his vision and confidence, predicting Facebook would have 300 million users, which it far exceeded.

Facebook's approach of prioritizing user growth over immediate monetization became a template for many startups, leading them to believe that following the 'Facebook Playbook' was essential for success, regardless of their business model.

The growth and user engagement on Facebook excited me, even though I wasn't a big user myself; the metrics showed it was gaining traction quickly.

The growth group we established at Facebook was crucial for our rapid growth, as it focused on leveraging our product to encourage community members to evangelize it to their friends.

Facebook's success was due to secure connections and ensuring that new users had at least 20 friends on the platform, which made it more engaging.

Facebook's success stemmed from our commitment to keep improving the platform based on user demand, which was different from my previous projects.
