CoffeeScript Roundup#coffeescript · · Peter Hoffmann
To get started I recommend the podcasts Changelog Episode 0.2.9 and JSCONF LIVE Episode 6 with Jeremy Ashkenas the lead developer of DocumentCloud and creator of underscore.js.
Another area CoffeScript might fit in is mobile HTML5 development. People already build iPhone apps with titanium and coffescript, 37signals iphone app chalk is built with CoffeeScript and Ryan Singer of 37signals mentioned building a Rails like framework for HTML5 Mobile Apps based on CoffeScript. The templating language for the framework seems to be eco and is already available on github.
