I work at a startup in New Zealand -- Hoist -- where we're building a platform as a service type offering entirely in Node. It seemed like the best choice when we started out a year ago and has paid off. It's fast and freeing to work with. It certainly might be harder sometimes than "established" languages but it's far better regardless. I'm so glad we're not using Ruby, personally, and my feeling is that Node is the new hotness. We share an office with another, funded startup that's also building in Node.
