Gnome is heading to its demise. I don't really understand their point. They keep messing up with power menu. 3.4 was shipped without all power options. 3.6 doesn't have logout or hibernation/suspend. Notification system is messed up. It is always hidden and you can't really right click.

Ubuntu Developer's are also thinking of switching from developmental build to stable build for Ubuntu. Nautilus has been put on hold. I will not be surprised that Ubuntu will fork Gnome and develop its own variant.

Transmission developer sums it up.
