The original gnome design document from 2009, or so, had some ideas in it that made me really hopefull. Even now it has a great technical base. I've seen some good ideas about how to make GS more useful (which have a chance at being implemented if Fedora starts moving away from upstream Gnome). Things I haven't seen from any other DE.
The one technical change Gnome needs to make is something like windows power shell integration, or osx automator (frankly, this might be better created at the fd.o level with a new dbus interface schema for scripting/recording user actions).
If the Gnome group wasn't given so much autonomy rh ux experts could've pointed these problems out early on.
