Why can't I see node.js hello world server on my mac?

I'm doing the tutorial here:

http://nodeguide.com/beginner.html

I got everything working up until this point:

var http = require('http');

var server = http.createServer(function(req, res) {
  res.writeHead(200);
  res.end('Hello Http');
});
server.listen(8080);

when I run the above using node hello_http.js it doesn't exit as expected but then when I view localhost:8080 in the browser or curl it there's nothing. When I curl I get curl: (52) Empty reply from server.

How should I look for the problem? One thing I should add is that I was playing around with cherrypy a couple weeks ago and when I visit localhost in my browser i see the cherrypy favicon. Is cherrypy interfering with this in some way?
