Personally I think we shouldn't move away from the concept of: URI <=> resource, just for some short-term gain. I think that metaphor will be a lot more useful in the long term.

What we may do, and to be honest it's starting to happen already, is to get rid of the address bar as an always-visible user interface feature. It could just be an overlaid window for those times when you actually want to type in the url (or if you jus want to check its value) that disappear once one click enter. And to be honest this is already happening in mobile phones where space is limited.

The breadcrumb idea, especially if as customisable as the author suggest, should be done in the site... which we already can do.
