Facebook is doing a great job of making everything you do on the web more transparent to your friends. The company's new programming interfaces, however, are doing a great job of making you more transparent to the websites you "like." And that poses a risk that nobody at Facebook is really talking about.
With a single click on a website, you could give up your contact information, location, age, and a good deal of information about your friends and family. For marketers, that information is gold. And for identity thieves, it could be excellent ammunition.
