Are there examples of large(ish) projects or production websites using primarily CoffeeScript?

It seems like CS has a fanbase among purists who enjoy the syntactic elegance. But in more pragmatic environments the extra pain in the develop-debug lifecycle would seem to be a showstopper. I just wonder how many developers end up voting with their feet when confronted with that choice in the real world.

P.S. Another argument against that wasn't mentioned: CoffeeScript represents an additional barrier to entry for opensource projects. Shipping compiled JS code is not unlike shipping a compiled binary... and if you want people to participate and contribute, requiring CS knowledge is an extra hurdle that most JS devs will shy away from.

I agree wholeheartedly, hence the initial question...

Here's a few examples of production sites/apps off the top of my head:
