Everybody else has decided that everything must change drastically, and even worse ... said change is completely different everywhere. The days of installing the OSS packages (Firefox, Pidgin, Transmission, mplayer, etc) and using Windows, OS X or Linux almost the same are over. Native-looking cross-platform applications become more impossible with each passing day. The ones that remain do so by using the old paradigm anyway (Pidgin, Transmission, old Firefox, etc) or simply doing their own CSD rendering entirely (Chrome, Chromrefox, etc)
Even for those who like the changes to their specific environment, I'd caution you ... if they so freely changed things with no choice before, nothing is stopping them from doing it again in the near future. You should never be too supportive of radical, forced change; for one day it might not be the change you wanted.
Funnily enough, there are only two things I need from the traditional paradigm: Window buttons in the panel (so I can hide windows by clicking their buttons in the panel), and panels than can be set to be vertical. Everything else that is new in Gnome 3 I pretty much like, but these two things I cannot get in Gnome 3.
So I run the Xfce desktop, but with all Gnome 3 apps, like gnome terminal, gnome file browser, etc. The Xfce alternatives I have uninstalled.
Well, I guess that just means hail to choice in the Linux world; you're happy with a traditional/conservative xfce and I'm happy with a more minimalist/moving GNOME. Cheers.
