Maybe this is naive of me to say, but wouldn't it be wise for Facebook to focus on new/different products, some of which may not be directly or even tangentially related to its core product. Isn't the goal to eventually diversify your revenue streams? Granted, 95 percent (or more) of Google's profit comes from search, so they're not exactly exemplar of diversification. But they do have a range of products, some of which are beginning to generate solid revenue (Google Apps comes to mind).
