"Most will recognize KDE and Gnome are the two biggest
of the lot, with XFCE coming in a close third. Each window manager
(WM) has its unique advantages and disadvantages, quirks, faults,
failures, successes, and surprises. For those who are bent on
bashing KDE4's numerous failures, decrying its seemingly premature
release into mainstream use, I wish to remind you of something:
This isn't the first time it's happened.
"And before the Gnome zealots have a chance to point fingers and
mock the KDE zealots, let me remind you as well that you're in
common company, as Gnome has done the same thing as well, and not
only once either. I remember back in the early days of KDE, mostly
after the 1.x days (The 1.x series was alright, but certainly never
good enough to be mainstream at any time) that KDE always suffered
a growing period shortly after it's point zero release."
