Just saw this story appear on the wires.
Google is battling against Facebook and for good reason. So much data and service is going through Facebook now especially traffic-wise, that Facebook is turning into a search engine by default and a powerful one too. Because FB has such on time responses people get news and other data in real time.
This is why fresh info is a must nowadays. Relevant data and copy to meet the demands.
If Facebook does go into the search engine market there's going to be one battle that'll change the face of the internet.
