In previous threads heroku and its limitations were discussed. This is a fantastic update about the status of heroku. I really love the promise little-deliver much approach heroku has taken. Even as a paying user this update was a pleasant surprise. Anywho, this will open back up the door on free high quality mud hosting via a project like haikumud. I'll probably do an update on that soon with it built just for that purpose. This update does much to eliminate almost all of the limitations heroku previously had.
