What Facebook is doing?

Have you ever play any Facebook games? I would say the founder of Facebook decided to open the platform for anyone to design different interactive games for users. It was a really smart move.

'FarmVille', 'Hotel City'  'The Pet' etc one of those you might be playing in your daily life. Apart from keeping users interested by all different games, Facebook can also obtain people's personal informaion , such as the date of birth and their interests.

When you are play games on Facebook, you are being marketed withour your knowledge.

Facebook is a global pheromone?

OK, lets get to the topic. Facebook. Can you tell me the last time you asked a person to add his/her facebook and they said they do not have one?

For me, the last time I asked one of my workmates from Russia his facebok and he said to me he does not have facebook and he even said to me facebok is not very popular in his hometown.

Do you think facebook is a global pheromone? Why do you think that?
