A good reflection of the world today.
Deep down inside social networking are advertising machines that bait, hook and drag "people" along -- whichever way they think would make more money for them. Yes, all (facebook, google+, line, linkedin,...) are building up followers so they can charge more for advertising. Internet (connection) providers are laughing and rubbing their hands -- happy.
Ask, ourselves how many advertisements we see while we surf the Net? And who pay for downloading these advertisements?
