On the first page of Facebook’s prospectus for its sale of stock to the public, it pegs the number of its “monthly active users” at a whopping 845 million people. The social networking site arrives at an even more astounding number when it comes to “daily active users”: 483 million people.
Those are some huge numbers. If it is hard to believe that so many people are clicking on facebook.com every day, that’s because well, they aren’t, exactly. Those eye-popping numbers should have an asterisk next to them.
