Do People Really Enjoy Snowball Wars?

Over the past few weeks, one of the fastest growing applications on the Facebook platform has been Snowball Wars. The application has seen exponential growth and a quick look at their growth chart (shown below) illustrates that the application’s growth has almost been perfectly exponential. It leads me to wonder, do people really want to play Snowball Wars?

While developers often search for a quick way to attract users, I have to assume that this application is using some other strategy for attracting users.
