A recent blog post by Ted Dziuba claims that Node.js "is a cancer" and fills out a few hundred words of inflammatory laden "proof" to make his point. The post makes a few good points but is largely off base. Perhaps the most sticking point is that CPU intensive tasks make Node servers become unresponsive, but I have a clever answer for him. Another issue he raises ("JavaScript sux") is, well, as a longtime Java programmer who used to work in the Java SE team at Sun, I've had my own moments like that, but really JavaScript is quite a nice language especially if you stick to the good bits of JavaScript.
