My tuppenny worth:

On the subject of Fedora, I've had no major problems with FC3, had
'some' with FC2 (but mainly on laptops, really) and waaaaaay too many
with FC1.

"is" Fedora 4, only frozen.  Also that (IIRC) Scientific Linux is built
on top of RHEL 4 (and hence is "like" Centos plus add-ons if it doesn't
actually share de-RH-logified rpms).

You remember accurately. Scientific Linux is <current_version_of_RHEL>
built from (open) source, minus anything that _may_ cause licensing
issues.

RHEL may be carrying the stability thing to a fault.

It's not entirely fair to criticise RH for the relative sloth of the
release of new RHEL versions. It _is_ 'Enterprise Linux', after all, and
I'd guess the air would be thick with lawsuits if J Random MegaCorp were
left exposed due to insufficient testing on RH's part (or Oracle's, or
Fluent's etc on the certification front). In this realm, though, I agree
that it can be an issue.

Where it is worth parenthetically noting that Centos 4 "is" RHEL 4 which
"is" Fedora 4, only frozen.  Also that (IIRC) Scientific Linux is built
on top of RHEL 4 (and hence is "like" Centos plus add-ons if it doesn't
actually share de-RH-logified rpms).

Regarding FC -- FC 1 sucked -- sort of a destabilized RH 9 and no (good)
support for x86-64.  FC 2 was pretty good and by the time it got turned
into Linux at Duke (FC2 plus enhancements and fixes) it was very stable and
has run on both cluster nodes and desktops for a long time, since we are
updating only every other FC release (and will have a linux at duke based
on FC 4 "soon" this summer).  FC 3 is running on the laptop I'm typing
this on (and a few other systems in my house) and seems to work very
well and contain significant enhancements of various sorts relative to
FC 3.

However, my broader experience is that with distros your mileage ALWAYS
may vary.  People tend to have a negative experience (often because of a
quirk in their particular combination of hardware) and then write a
distro off, but if one perseveres and gets a clean install it will
probably run just fine -- not that crazy given the tremendous overlap in
source and build across distros.  For example, saying that you "like"
only some of Centos, RHEL, SL, or FC but not the rest is almost
certainly due to user error or because you dislike something about the
philosophy of one or the other, not because there are deep substantive
differences in install, basic package selection, build methodology, etc.

I personally think that FC is only marginally less stable than the RHEL
clones, for example, and in anything but a brand-new FC release the
update stream almost certainly fixes those relatively few initial
problems.  This makes yum a key component of any install, but WITH yum
one has a truly impressive range of prebuilt RPMs available with the
various add-on repos.

The dark side of the RHEL clones is the slowness of their advances.
Centos 3 was running GSL in some really early version LONG after
significant new functionality and bug fixes were available in the STABLE
RELEASE version in FC.  Stability and update stream are just great, but
I personally think RHEL may be carrying the stability thing to a fault.
The kernel, also, can be a real problem if "stabilized" for too long --
two years is a LONG time in hardware space; lots of products released
and supported in more aggressive kernel update streams, lots of
improvements in the kernel itself.
