But isn't that a testament to Farmville rather than Facebook? My grandma is on Facebook because I am and others she knows are. This is ultimately what sustains Facebook's success: The network effect. It's the "cool" thing to do. It's where everybody is, so you need to be. Despite that, the network effect is very volatile. It's not something you can easily sustain. MySpace was where everybody was at one point too. Facebook is fooling themselves if they think privacy isn't one of the areas they need to innovate.
