I have a number of sites that use Javascript navigation menus.

From what I've heard, the conventional wisdom is that links from the home page into other pages of the site are important. With the Javascript menu, we have no internal links (at least not links that are visible to search engines).

However, we have created and submitted a sitemap.xml file. From what I understand from Google's webmaster forums, this is the 'correct' way to direct Google to all the pages of your site, and also allows you to specify relative weights, rather then relying on internal links to transfer PR.

Comments? Do properly constructed and maintained pagemap.xml file make internal nav links moot?
