Our game Mahjongg Dimensions launched on Facebook in January 2010, currently has 1.3 million monthly active users (MAU) and is adding 30 thousand new players per day. This may sound like a pittance compared to games like Farmville (and it is) but it's still dramatic growth. To compare, a game website I've had online for seven years, and put an equally small amount of marketing dollars behind, has 400,000 unique visitors per month. So with Facebook, one game was able to achieve in two months what a website with 100 games couldn't do in seven years. A stat like that makes it easy for anyone to become a believer.
Granted not all games and all apps will succeed on Facebook, as evidenced by the thousands that languor with 500 MAU or less. But for those who take the time to create something unique, fun, and viral there is no better platform to be a part of right now. Marketers who until now have only dipped their toes in the water are (rightly) jumping in head first."
