Re: Simpler solution
Couldn't agree more but the words that define Facebook and how it makes money are "captive audience". Ask anyone running a business, no matter how small, if they'd like access to a potential captive audience of 1.5 billion and most will jump at it.
Facebook has nothing to do with people being social, it's all about having a captive audience for anyone with an axe to grind or a product to sell.
