Differences between default Gnome and Fedora

[Steven Garrity <stevelist silverorange com>]

I've been wondering about what Fedora does differently in the Gnome 
desktop than default Gnome. I'm not in a position to be able to easily 
install both to compare (I just have Fedora Core 1 installed).

I'm wondering what differences there are - and why. I would like to see 
some discussion as to the value of each/any differences - is it worth 
keeping different - and if so, is it worth looking at upstreaming to Gnome.

I'm thinking of stuff like the dock/quicklaunch area and the 
fedora/start menu, etc.

Thanks,
