Facebook is really proud of few things. For example that Facebook is biggest social site that unite 1.5 billion users.
If we count that the earth has seven billion people it is almost every fourth men on planet. It is thing you can be proud of. Now Mark Zuckerberg Harvard drop-out can be proud again. One of seven people on the planet log in to Facebook. Yes yesterday for the first time more than billion people logged into Facebook. Of course not all of them in the same time but even that is remarkable achievement in context of world-wide social course of events. What is the next achievement? Two billion users on Facebook?
