The Debian Project...
...is reading my mind!
I didn't tell anybody, but a couple of months ago, when I finally had time at work to upgrade my work computer desktop from Squeeze to Wheezy I also switched from GNOME to XFCE. Now I read via LWN that Debian is doing the same, at least for a while :)
BTW, I knew newer GNOME was different (had seen it in Fedora 18 for example), anyway I installed it (because I was lazy enough just to apt-get dist-upgrade the box) and tried it.
Maybe it's me, becoming an old dog which doesn't want to learn new tricks, but in order to get my work done as fast as usually I had to install something usable, hence went back to XFCE. I had to manually convert GNOME panel launchers to XFCE launchers but, besides that and some missing applet I'm pretty happy with the switch.
