Never mind that RoR is a web framework, this kind of thinking, that some technology is a silver bullet, or that another is unusable because it is less popular, or that six so-so developers are worth as much as two or three good ones because they're easier to find, is a real problem. It's immature to say out-of-hand that some language, for any application, is "too risky" when it has a good industry track record.
