Who is that everybody wanting gnome3 to look like gnome2? For that sentence, it looks like that "everybody" want to freeze in time forgetting the world is constantly changing. Gnome Classic (as seen on Clarsen's blog) is nothing more than an extended Gnome Shell
No one is asking to get rid of gnomeshell, its great for tablet users!
Surely everyone would be happy if gnome3 much closer resembled gnome2 but with GS as an option at point of installation.
Or as a "Tablet mode" option in System > Preferences.
