You all know Gnome3 has failed horribly for people that want to do anything but browse for covers in iTunes. I have been using Linux since when men were men and wrote their own device drivers (1994, Linux 1.x, Slackware floppy series) and I do believe the Linux desktop currently is in crisis. A serious crisis.
The only users that could possibly like Gnome3 are the users that will never use Linux but are perfectly happy with Windows 7 or OSX. I do not believe trying to cater to beginners is what Linux need to do. It's a tool for more advanced users with different demands and I am perfectly happy if it stays that way. Linux is user friendly enough if you got any interest in learning and reading some.
I, for one, have switched to XFCE a long time ago. While I'm not 100% happy, bash scripts and simple hobby hacks let me do what I want to do without getting in my way and I really got no serious complaints.
Gnome is going to die if it doesn't change, because the user base it wants to attract simply isn't available.
