Whilst I have internal links where relevant within content pages - and not going overboard as, like honestman, figure they may seem distracting - I also have several menus.
Retain a navig menu throughou (and only a few days ago, did away with top navigation); and have section menus, chiefly with links to main articles in these sections. These menus appear on pages in these sections; I also have several of them on home page, as I've found direct links from home page can g=be big help.
These menus help interlink the site, without going overboard with links on any one page. Also help with variety as people move around sites.
