Just watch the film "The Social Network" and got inspired by Mark's (the creator of facebook) genius. Just can't imagine how people can be so intellectual they turn the world upside down. I mean, the world was never the same again after facebook. Now, everyone's into it- as it is a convenient way of meeting friends no matter where they are in the world. Truly, it was a milestone in the history of mankind..
thank God for such kind of minds.....
