Gnome has become an abysmal piece of drek not worth the effort of spitting on. The only reason I ever use it is because some configuration options for various distros are only released for the Gnome desktops on those distros. I use KDE day to day, with the sole exception of the Rhythmbox music player (which itself is just a "lesser of evils" choice -- every Linux music player I've tried sucks in some way or other.)
Gnome 2 was usable. I liked Gnome 2. I would have happily stuck with Gnome 2 and reasonable enhancements to it.
But nooooooo, the development team for the Gnome project knew "better" than everyone else how a computer should operate. They totally screwed the power user with Gnome 3, creating an unholy abortion that doesn't work well with mouse and keyboard and doesn't work well with a touchscreen. It is the worst of "both worlds", and even implements a number of widget metaphors that testing showed people didn't like as far back as 1990.
The Gnome dev team is full of egotistical idiots, and I, for one, can't wait to see them all hit the curb.
The software is open source. If the project dies, the useful bits will be picked up and forked, and all the drek they've shoved down user's throats can wither away and die a horrible, painful, screaming death as far as I'm concerned.
