Amen - I quickly learnt node.js to build http handler for the callback element of a tool I am building using authority labs - for what we need its the dogs nuts.
Yeah; maybe if you're using it to build a Big Fancy Webapp it's actually a stupid idea, like if you use a Swiss Army Knife to do carpentry and build a home, you're probably doing it wrong.
I'm using node for a small tool to analyze network traffic. The author of this drivel can cope. :P
