Hi myrrh! I'm sure that the good folks in the Accessibility and Usability forum can do a good job of addressing this matter. :) We tend to stay focused on technical concerns in the Javascript forum. ;)

Personally, I think that some particularly complex sites can do well with multi-tier navigation. The main concern to me is making sure that javascript-disabled users (and therefore search engine spiders) can still find the navigation elements.
