Ya, I'd tend to agree with Mark here -- by too broad a definition linux
itself is one big rolling beta release (a point of view M$ would
cheerfully espouse to its customers and probably does).

Besides, FC is as stable and usable as RH ever was (he says typing at
his FC2 laptop while working in his various FC2 and FC3 workstations and
with his FC2-based cluster).  RHEL can also be spelled "stagnant" --
having a really long release/support cycle (however valuable it is to
certain customers) also means that new features take a long time to

It's easy enough to stabilize the FC cycle to a bit less than the
frenetic pace the distro itself uses -- just "issue" (use in production)
every other release in your environment.  For example we're using FC2 in
production now, although most of our high end linux humans are running
at least some FC3 systems (I am, for example).  When FC4 come out, we'll
package it up for production, skipping FC3 altogether.
