Geo-chat with node.js, Express, Coffeescript, MongoDB and Google Maps API v3

This is a simple location-based chat, which I wrote to practice in Coffeescript, geospatial indexing in MongoDB and new version of Google Maps API. Drag marker on the map to your location, set the area you want to listen to, and chat with people in the area.

The chat is using Socket.IO for realtime communication.

Google Maps widgets shamelessly borrowed from this article: Fun with MVC Objects, and Chat application is based on the example in Express repo.
