I'm amazed at how support for Fedora has dwindled, 3 years ago if you posted this it would have had a lot or comments and discussion going on about the new release. Has Ubuntu taken these followers or another distro?
Fedora is still my personal distro of choice and, if anything, seems to be making up some loss in popularity because of the Gnome 3 / Unity debate. Still, at the end of the day, choice is what Linux is all about
At one point Ubuntu seemed to be perfect for the average office end user and I performed a few v8/9 installations but reverted most to Fedora because of problems with things breaking on updates and upgrades, Fedora has seemed to be less "Bleeding Edge" in this regard in recent releases.
ATM the current preferred desktop distro for my clients is Fedora 14 or CentOS 6 both with Gnome 2 - data capture operators scare easily and Gnome 3 & Unity need to mature some more before exposing them

.
For the Linux home user I suspect that Linux Mint could well overtake Ubuntu in popularity in time to come.
