For a site with a 7 link navbar I've recently concluded that there are 2
contradicting requirements.
For linear/1 dimensional access (screen readers/speaking browsers) of
the sub pages a single link back to the index page would be ideal,
thereby preventing the imo pointless reading out of the navbar links on
every sub page.
This doesn't apply to 2 dimensional (visual) access of the same
documents imo, users can effortlessly skip over the navbar, and it
facilitates quick "zapping" of a site's content.
This is one reason why the navigation should always appear after the
content in your HTML, and use CSS to reposition it to where you want it
on the screen. A closely related reason is that search engines will
then weight your content higher than your navigation, rather than the
other way around.
