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 its emphasis on real identity and the ability for users to share their content, which was missing from other platforms at the time.

For social media platforms, connecting users with their friends quickly is essential; without this connection, users are unlikely to return due to an empty newsfeed.

Facebook started as a service for Harvard students but expanded because almost everyone has friends and family they want to stay connected with.

Even if a university had built a social network, Facebook's ability to allow users to share more content and connect in meaningful ways would have set it apart and driven its success.

Facebook has pivoted many times, evolving from a college platform to a broader social network, demonstrating the need for flexibility in business.

The human brain is wired to process social interactions, which is why Facebook focuses on connecting people rather than just meeting new ones.

I realized that Facebook was an unstoppable force in social networking, and that competing with them was a significant challenge.

Successful companies like Facebook and Yelp demonstrate that the real value often lies in the network or content, not in charging for access to the service itself. The real value of a network like Facebook is not just its features, but the connections it facilitates among users, which is why it became so disruptive.
