Vincent Untz sent a message to the Gnome Devel list this morning regarding Planning for GNOME 3.0. Citing the belief of the community that GNOME Is lacking excitement and vision, some of the core release team members started planning for the (mythical) GNOME 3.0. This is basically a call to arms for discussion about what 3.0 will be all about. Well done I say, especially since GNOME 2.0 was released June 2002.
