Why CoffeScript?
I see more and more references to Coffeescript, the latest being http://chalk.37signals.com

I have looked at the documentation, and I just have to ask - Why?

Why would I bother to learn Yet Another Language that compiles to JavaScript?  Why would I not just write the JavaScript itself?  Is it just the terseness?  For the thrill of trying something new?  Because it has 'Coffee' in the name and therefore must be good?
