Yup, Facebook launched an API to the public yesterday. You can see more information and a list of calls to their database on their documentation page. TechCrunch and ProgrammableWeb both have coverage on it. There is already a Mashup created that was put together in 2 hours by the developer. It is called Facebook Friend Mapper, and guess what, you can see your friends as they are geographically located on Google Maps.

I tried it out quickly, and it is pretty interesting. As you can see from the screenshot below, most of my Facebook friends originate from the East Coast.

We’ll soon see what other developers come up with.
