Reading over this ( http://gonzalo123.wordpress.com/2011/05/16/web-console-with-node-js/ ) , I felt this was a pretty good and relatively real world example of nodeJS’s capabilities. I did find one line near the end very poignant and reflective of my own opinions at the end of the show & tell post

I don’t know if node.js is the future or is just another hype, but it’s easy. And cool. Really cool.
