[Commentor] LC-297 Ian Jacobs [Comment] * If you really mean "should be enough" then say "Provide between 2-4 links at the top of a given page for navigation to important parts of the page." That seems to me to be more useful than saying "minimal navigation." Find the 80% point, say it, and then let people adapt for other cases as required (and explain to them when they might encounter those cases). * In the same spirit as my comment on the previous point, you might rephrase this as:[Navigation helps in small doses] Providing 2-4 links at the top of a page to important content in the page facilitates navigation. Many more than that hinders navigation. [Commentor reply] yes [Working Group decision] 
We have reworded the explanatory text about navigation bars, noting in particular that the navigation bar shouldn't prevent the user from seeing the core of the content.
