Facebook isn't an application, it's a company that makes money by creating and maintaining a social forum. Facebook may use computer software "applications" to further this end, but one mustn't confuse the method with the goal, especially when one considers that the same goal could be achieved using different methods.

Yes, I can see that. You also think Facebook is an application, like Excel. It isn't, it's a company.
