This doesn't directly relate to the article but does relate to essentially every single comment ever on slashdot being a hate on for GNOME 3. There are several different arguments that people generally make so I'll address the ones I can think of.
1. GNOME 3 is different than [insert other DE here, usually GNOME 2] so I don't like it. ... are you serious? I mean it may seem childish when I state it that way, but probably about 50% of the arguments against G3 don't consist of anything more than that.
2. The interface is too simple
Well what do you want? Whenever I'm looking for ways to change my own UI, the most easily findable ones are always how to simplify it, I assume that functional simplicity is a popular, and good, thing (especially among the non-linux users who everyone seems to think GNOME 3 will drive away).
3. I can't customize it enough
Well, yeah. Because it's new. The vast majority of customizations for GNOME 2 are third party programs and/or themes, which are available because it's been out for so long.
Anyways I could find more, but the point is this, there is nothing inherently wrong with it, one of the beautiful things about the linux world is that it gives you the chance to choose, not just choose the distribution, which widely vary, but your DE, IDE, dock, system monitor, terminal, shell, hell, you can even change things in the kernel if you know what your doing. This may astound people but I REALLY LIKE GNOME 3, and HATE GNOME 2. However I realize that this is a matter of personal preference and that there is nothing really wrong with gnome 2 persay. I like having a launcher in the launchy sytle (which is really efficient by the way, you hit one button and type in what you want), and dislike the menu system in GNOME 2. Does that mean it is bad, NO, it means I have an opinion, but I do think GNOME 2 was executed well.
So go use something else if you don't like it, and stop telling me that I'm the stupidest person on the face of the earth for an OPINION that is different than yours.
