So... Facebook has some code you can put on your page and you have an instant like button. Well... what if Facebook starts providing a neat little bit of code that also embeds an ad? If the Like button knows who you are... so will the ad widget. So now they are serving "Facebook ads" on other sites. Of course that is what Google does with AdSense... but does Google know as much about you on that page as it does about that page? I could see it possible for Facebook to grab eyeballs on other sites... sites that are currently monetizing with AdSense. Not that I'm convinced they would make a dent with this approach... but you can't just compare the ads ON Facebook to the ads on Google search. If Facebook was putting the ads on pages that had a different focus than what you do on Facebook... there is a chance.
