Facebook exposes its source code to the world

The source code for the front page of Facebook has appeared as a single blog post on a new blog called Facebook Secrets. Facebook told TechCrunch,

"Some of Facebook’s source code was exposed to a small number of users due to a bug on a single server that was misconfigured and then fixed immediately. It was not a security breach and did not compromise user data in any way. The reprinting of this code violates several laws and we ask that people not distribute it further."

A little worrying I'd say. If one web server is "misconfigured" then what else is?
