Perhaps a different way to state the same question is: What do I get by upgrading from FC5 to FC6 (to F7, F8, etc..) that I don't get by simply running "yum update"?
Basically, AFAIU, you get major version upgrades. For example, FC5 has GNOME 2.14 as the main Desktop. FC6 has 2.16. FC5 is not going to get 2.16. Ever. It will only get updates for minor versions.
