How much will you pay to be listened to on Facebook?
Facebook is having a Red Barn moment. If you ever played Farmville you'll know what I mean. Farmville was fun for the first little while, planting, pulling in friends to pet your cows or whatever they were doing. Then at some point you realize the game has a limit beyond which you need to pay to do better. You can't get the red barn unless you put down some actual real world dollars.
