This article does well to make newbies aware that there are other desktop/window-manager possibilities. However, it probably could have gone a little further, and it could have been a little more accurate.
Although the article did say that it was "... merely scratching the surface..." of the available desktops/window-managers, here's a simple link to a site listing and describing what's available:

There is a world of choice out there!
FROM THE ARTICLE:
"While GNOME shares similar goals as KDE, that's where the similarities end. The environment as a whole is completely different, and is reminiscent of Mac OS 9 in terms of layout. Whereas in KDE, all of the programs, launchers and applets are crammed into a single bar (which is why it's so large by default), GNOME splits this into two parts. On the top of the screen you will have your menu, clock and quick launchers. On the bottom, you have your currently used applications and also the desktop switcher. It may seem like an odd setup if you've never used GNOME before, but after some usage you will quickly understand how much sense it makes."
This paragraph includes a few of the many misconceptions involing Linux desktops/window-managers. The default layout of a desktop is usally determined by the specific Linux distro, not by the creator of the desktop/window-manager. Here is a screenshot of the default KDE desktop in the recently-released, mini-edition of Sabayon Linux:

As one can see, part of the task-bar is defaulted to the bottom of the desktop, and the other part is defaulted to the top. So, Gnome isn't the only desktop/window-manager that has this capability -- not by a long-shot. And, from looking at the KDE panel-configuration window, it is obvious that task-bars (and portions of task-bars) can be arranged in almost any way that one desires, including along the sides and corners of the desktop. I would guess that Gnome is just as configurable.
I'm also guessing that many Linux distros having KDE as the main desktop choose to default to the large task-bar to accommodate the 4-paned, square arrangement of the "virtual desktops." Perhaps the distro creators want new users to know that the square arrangement is a possibility, in case the new users are only familiar with the side-by-side configuration. At any rate, in KDE, it probably only takes three or four clicks of a mouse to change to one of the smaller task-bars, with side-by-side virtual desktops.
I don't know if there are prescribed, default layouts from KDE or from Gnome -- the screenshots from the KDE site show a few typical layouts with a few uncommon ones:

I couldn't find any screenshots on the Gnome site.
No reason is given as to why the Gnome layout shown makes so much sense. After years of reading the opinions of countless usability "experts," I believe that the best layout is the one that the user prefers, and there are zillions of other layouts possible in Gnome, KDE, ROX, WindowMaker, Golem, E17, 3d-Desktop, XFCE, *-box, JWM, Oroboros, PAWM, etc... By the way, I currently enjoy IceWM with one tiny task-bar on the bottom, with side-by-side virtual desktops (four) and with no icons.
FROM THE ARTICLE:
"When you first login to a new GNOME environment, you will notice how incredibly clean it is. The desktop only has a few icons (unless you have files already there) and the theme is simple, but visually appealing."
There are only a few desktop icons on the default Sabayon, KDE desktop shown in link above, and this condition is true of the default, non-Gnome desktops of many Linux distributions.
The visual appeal of a desktop or window-manager is subjective, and relies primarily on the specific theme/configuration that one chooses or modifies or creates. And themes are portable -- if someone creates a popular theme in one desktop/window-manager, that theme is often ported to other desktops/window-managers. Most of the established desktop/window-managers have a wide selection of themes/configurations.
FROM THE ARTICLE:
"All of that said, once you have GNOME installed you will have a desktop like seen at the top of this page. Although it's such a full featured DE, bloated is a word that doesn't come to mind. It's fast, versatile and reliable."
Again, it might be that not all Gnome desktops will appear like the one shown in the article.
Also, I don't know much about Gnome's current state, but I would be surprised if it has overcome the size and bug problems that have plagued it in the past few years. KDE is also huge, but, as I understand, it is easier to compile.
FROM THE ARTICLE:
"Fluxbox, E16, FVWM-Crystal"
"Warning: Hardcore users only! Minimalistic environments are just that. They are designed for a variety of users. First, you may have a super old machine that you want to set up as a file server. Or, you may want the smallest environment possible for performance reasons, or enjoy having a lot more of your screen available for windows at any given time. Lastly, you may be one of those Lunix hax0rs that would feel more more leet by using a more hardcore environment."
Let's not scare people unnecessarily. Fluxbox, E16 and FVWM-Crystal are incredibly easy to use. I'm positive that my 81-year-old mother could easily navigate through any of these three window-managers (she runs Mepis/KDE).
The true minimalist environments are Ratpoison, Ion, evilwm, BadWM, Stumpwm, etc., and these window managers are extremely fast and efficient. Here's a screenshot of Ion:

Hope this helps.
