Pick the language that makes you happy
For a company like Basecamp, you’d be mad to make your choice of programming language and web framework on anything but a determination of what’ll make your programmers the most motivated, happy, and productive. Whatever the cost, it’s worth it. It’s worth it on a pure cost/benefit, but, more importantly, it’s worth it in terms of human happiness and potential.
This is why we run Ruby. This is why we run Rails. It’s a complete bargain.
