The point wasn't that everyone should use it. The point was that it was trivial to pick up and use so I'm often surprised when people complain about how difficult it is to read. If I handed you a piece of CoffeeScript and you literally had never read the docs, but are a competent programmer who knows Javascript well, it'd be surprising if you couldn't just read it as-is and know what it's doing since you know it's just an alternative syntax for javascript.
