Please understand that I'm not trying to be combative here, but...

How is a user supposed to know:

1. gnome-shell == GNOME 3?
2. gnome-shell is available in F14? I don't remember it being
mentioned in the release notes or any list of features.
3. gnome-shell will irreversibly replace what the user is familiar
with in the next release?

So, now having discovered all of the above, the user can install F14
and gnome-shell, try it there and provide feedback on that version?

Better to change the default system and keep the old system available
for a release cycle, rather than provide a virtually unadvertised
preview version up to the point that it becomes the default and the
old system is no longer an option.
