Title: Hello all hackers from HackerNews.  We notice a new MMO was released by n01se and xkcd yesterday (September 26th, 2012) with multiple users flying around with a balloon figure.  If you got stuck, you can click your balloon guy and turn into a ghost to seamlessly move through the landscape unhindered by mortal barriers like trees and hills.   There was a problem however with the scaling of users on the system.  The max concurrency could only be 20 users at a time leaving many wonder where the MMO part of the MMO was.  We ripped out the non-scaling Node.JS code.  ENJOY.<p>Enter the xkcd World with Friends: http://www.pubnub.com/static/pubnub-xkcd/index.html
