We've built a product in coffee-script that is made for navigating websites and forms logging and scraping and pulling in data.

It's quite useful outside of rails in that sense I'd say. It could have just as easily been done in JavaScript but I'm not a fan of the syntax(fuck curly braces)

I'd maintain that just about anything out there can be used outside of the context you think of it in.

Asking if coffeescript is useful outside of rails is similar to asking is perl is useful outside of scripting, it's a poor and misguided conception that languages can only be used in a certain way or with a certain tool.

I'd say that's true much more often than not that if you know a language well you can build complex applications with it.
