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.

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.

In the early years at Facebook, we should have focused on iteration speed rather than building a large team and a polished product.

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.

We achieved rapid growth by embedding our forms on users' websites, allowing our product to spread organically without hiring salespeople.

Facebook's growth forecast was initially underestimated; they grew to over 2 billion users by being intentional about growth strategies.

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

FriendFeed generated a lot of buzz but struggled to grow because we competed with Facebook, which became a formidable competitor.
