Facebook's friends are its users. The company has over 2 billion active users, making it one of the largest social networks in the world. Facebook's stock price dropped after its initial public offering (IPO) in 2012 due to concerns about the company's ability to monetize its user base. However, the stock has since rebounded and is now trading at an all-time high.

As of July 2023, Facebook's stock price is trading at around $200 per share. This is a significant increase from the IPO price of $38 per share. The rebound in Facebook's stock price is due to a number of factors, including strong user growth, increasing advertising revenue, and the successful launch of new products and services.

Here are some of the key reasons why Facebook's friends (users) are valuable to the company:

1. Advertising revenue: Facebook's friends provide the company with valuable advertising revenue. Facebook sells advertising space on its platform to businesses that want to reach its users. The more users Facebook has, the more valuable its advertising platform becomes to advertisers.

2. Data collection: Facebook collects a wide variety of data on its users, including their demographics, interests, and location. This data is valuable to businesses that want to tailor their advertising campaigns to specific audiences.

3. Social networking: Facebook provides a platform for its users to connect with friends and family. This allows businesses to create relationships with potential customers and build brand loyalty.

As you can see, Facebook's friends are essential to the company's success. Without its users, Facebook would not be able to generate advertising revenue or collect valuable data. This is why Facebook is focused on providing its users with a valuable and enjoyable experience.
