Facebook: Do You Know How We Earn Money From the Users?

While browsing inside facebook, I came across an article,
not really of an article but a trivia about the social-media site. I don’t
know if this is legit, because some information that comes from the site is hoax,
since "trollers" are all over the place. Well, the trivia
came from a facebook page named, “Trivia Mania”.

The trivia was about facebook making money from its users,
that every person that makes a profile in the site adds about $47
to the entire value of the company. Well you will wonder how they will
make money from just creating profiles in their site. Here is the answer; one way
of making money is that the commercial ads for every click are charged.
There is a new way companies charging every conversion or transaction.
If this is legit, then the site is a growing investment from time to time.
