Building your brand with Facebook

Breaking away from all things football related and finding this gem of a vid. Is Facebook taking over the world?
The world has gone social and Facebook seems to be the way forward. Will it burn out soon or continue to grow?
Recently out at an event, Irelandinc.ie was asking for a card or mobile number of a potential contact and low and behold found herself being told to 'look them on Facebook'!! - the horror (sign or the times, maybe).
