Seeing Linux clearly: Demystifying KDE and GNOME (iTWire)

The author also appears unaware of the distinction between a window manager (kwin, metacity)
and a widget toolkit (qt, gtk...). Viz.:

"In fact, most all software will run under both KDE and GNOME and will correctly adopt the
appropriate user interface so as not to cause offence. After all, the programs are merely
requesting “a button” or any other visual element, and it is up to the window manager – within
the desktop manager – to draw it as it sees fit."

Seems that this article is likely to cause as much confusion as it resolves...
