It's been obvious for a long time that the GNOME developers don't care about their existing users. They've been dumbing it down for a long time to attract new users, without any concern about losing existing users, e.g., removing Emacs key bindings, changing to and from spatial navigation, etc. I have a hard time believing that it's a viable strategy, but who knows.
I spent a few days with GNOME 3, then moved to XFCE. It doesn't seem like that much of a step back from GNOME 2 to me. I'm much more productive with XFCE than with GNOME 3, so I don't care what the GNOME developers do from here on out. I'm not "threatening" to go elsewhere; I've gone. The GNOME developers won't care, and that's fine.
