What do people do on Facebook?

They chat, share photos (more than 250 million new ones each day!), post videos, stay in touch and share personal news, play games, plan meetings and get-togethers, send birthday and holiday wishes, do homework and business together, find and contact long-lost friends and relatives, review books and recommend restaurants, support charitable causes....

In fact, there’s very little people can’t do on Facebook. It’s sometimes called a “social utility.” Like a power grid, it provides the supporting infrastructure for the constantly changing everyday activities of hundreds of millions of users, 24 hours a day, 7 days a week. The amount of activity on Facebook is almost inconceivable. Every month, users add 30 billion pieces of content (comments, photos, Web links, blog posts, videos, etc.) to Facebook.

In effect, the “product” of Facebook is a living thing that changes constantly.Unlike the media we parents grew up with – books, newspapers, and even radio and television – it’s “user-driven,” the collective product of its millions of users’ lives (not just their social lives), updated spontaneously, moment-by-moment around the world. It’s a large swath of the wired and wireless social Web that increasingly mirrors all of human life.
