I wish GNOME would have first made a GNOME 2.4 release which would have been GNOME 2.32 ported to GTK 3.
Instead of jumping at GTK 3 and GNOME 3 at the same time.

Then forks (MATE) would be using GTK 3 now instead of GTK 2.
I hope that MATE keeps the GNOME 2 spirit but gets ported to GTK 3.

I use Ubuntu 12.10 (alpha) with the gnome-classic-session which is like GNOME 2.32.
