Why is FarmVille so popular?
People who are addicted to playing FarmVille, think the game is stupid and boring, but say they just can't stop playing.
I know you would be wondering why so many people play "FarmVille" if it isn't fun?
The simplest reason is advertising. "FarmVille" is advertised like crazy all over Facebook, so it's always in everyone's face. This advertising is incredibly effective, because it is so immediate: You click on the ad, and you're playing the game.
FarmVille's parent company, Zynga, isn't the only one advertising it though. Users are constantly advertising the game to their friends, too, through "viral" channels on Facebook.
The less obvious reason that millions of people are addicted to FarmVille is that there's a sense of social obligation to play. If you don't play FarmVille, your FarmVille friends suffer.
