To prevent delays that have become all too common to the Fedora Linux camp with no release in recent time having actually shipped on time, Adam Williamson of Red Hat who serves as the "Fedora QA Community Monkey" proposed the idea of moving to a more rolling-release model rather than the static releases that have been going back to the Fedora Core days.
This isn't the first time that turning Fedora into a rolling-release distribution has been proposed, although this time it actually comes from someone within the camp (and a Red Hat employee, although Adam's just expressing his own personal views) rather than comments from some random person.
While Adam Williamson emailed a serious proposal about considering Fedora as a rolling-release distribution, so far there haven't been many other Fedora developers/users in favour of such a change. Most of those expressing dissenting opinions are concerned that Fedora would just become too unstable and that a rolling-release model isn't too different from the "Fedora Rawhide" development packages as it stands today.
It's unlikely that Fedora as a rolling-release will get picked up, but for those interested in some weekend reading, here's the thread.
