Navbars must go

While mining Bohmann Usability I came across an interesting article suggesting that navigation (global navs, i presume) must go. Kristoffer Bohmann argues that "Users mainly ignore primary navigation bars because the information featured is less relevant to their tasks." I believe the main argument that should be extracted from this article is that users need more relevant information once they've dug deeper into a site. I don't agree with the idea that global navigation should go away, if that's also what's suggested. You might also be interested to see Bohmann's annotated collection of navigation bars and to read the related articles.
