Well guys i have noticed this that many people on facebook are addicted to the games like Mafia Wars, Farmville and many mroe Zynga games ... is that one reason behind the success of Facebook ???
I think so. I used to visit Facebook rarely but since I have started playing Mafia Wars, I spend a lot of time there. And I am aware of others who do the same. So, the games have played an important factor in the success of Facebook.
