"Over the past two years, EveryBlock has been funded by a grant from the Knight Foundation. The purpose of the grant was twofold: to launch this experiment in "micro-local" news, and to release the source code. Today, as our grant period comes to an end, we're fulfilling that second purpose. You can read more about the open-sourcing and download the code at our source code page. (Keep in mind it'll probably make sense only if you're a web developer/programmer.) We hope this extensive code base helps spark lots of great work." - Will Sullivan
