These forks of GNOME 3 have confused me right from the start. You see...GNOME 3 is designed to be highly customizable. Building a GNOME 2-styled user experience (the top and bottom panels, the Application menu, etc.) on top of GNOME 3, utilizing extensions, has been done since almost the very moment that GNOME 3 first launched back in early 2011.
The talented developers that forked GNOME 3, for this purpose, (such as the Cinnamon crew) have just wasted a significant portion of their time. That time could have been spent working with the GNOME team to add new functionality and improvements. And that loss of time and progress is a major bummer.
