Seriously? You'd do that? You'd totally provide your personal information to yet another third-party application in trade for "free" coins to use in that virtual sharecrop you've got going over on Facebook? Do you really want a pig that bad?

Well, even if you claim you wouldn't do that, there are plenty out there who would. Yes, they'd expose their info to exploitation, just to move that much faster toward "Level One of Daffodil Mastery" within the faux feudal system that is "FarmVille." If not that, then for a bounty to pay friends willing to fight an enemy in "Mafia Wars," to upgrade a pretend panda in "Pet Society" ... or pay for whatever it is y'all Yos do in "YoVille."

Social network gaming apps are making big news for the big bucks they haul in by the bushel. FarmVille, for example, boasts more than 60 million members, not to mention a plethora of fan Web sites.

But those hundreds of millions of dollars don't come from hundreds of millions of Facebookers playing for free - or even those who pay real-world money for in-game currency. The real cash cows are the advertisers who pay game developers for serving up customers on a silver platter. (That would be you.)

How much cash? Well, Zynga, maker of the "Farmville," and "Mafia Wars," among other social network apps, boasts an annual revenue of $200 million. Playfish, maker of games such as "Pet Society" and "Restaurant City," has an annual revenue of $75 million. And Playdom, with its "Mafia Wars" predecessor "Mobsters," as well as the popular "Bumper Stickers," is looking at $60 million this year.

Ka-ching!!
