That said, businesses that want to create a dialogue with their customers use Facebook. Granted some companies, such as GM, that Facebook isn't so great for advertising, still value having a social relationship with their customers. GM has 380,000 "Friends" on Facebook I'm sure it won't un-friend just because they aren't clicking on its ads.

These are ten ways Facebook might try to rule our lives using its vast social networking power. But that doesn't mean that it will, or that if it tries, it will succeed. Back in the day when Microsoft was a dominant player, people predicted that the company would have a pervasive element in every aspect of our lives -- and look where Microsoft is now. It's not dead, but it's certainly not everywhere.

Plus, if you're worried about how Facebook might rule the world, you may want to take a look at Google -- and just how much data of yours that search engine actually has.
