I think the point is not that Rawhide is now broken (after all, it is supposed to eat your babies, right?), but that nobody uses it is so often broken for a long long time, because not many developers uses it as their production machine. Old-time Rawhide used to be broken often (I was told that "there are days when Rawhide actually boots up" when I was asking about its usefulness in approx. FC6 time frame), but it was also rapidly fixed because the developer's own machine was broken as well.
Not saying that it is good or bad (yes, I was using that "update in time of Alpha policy" as well when I was still using Fedora as my main system ;now I have to use RHEL for the work-related reasons), just clarifying what I read in the original article.
