Well, it is mainly an accessibility and a usability thing. Personally, I
do think a navigation can have non-underlined links and also no visited
link state, if it is obvious that it is the main navigation. Links
inside copy text should have both, underlines and states. Nielsen[1]
published some revised guidelines on links lately, and they more or less
say the same. Joe Clark [2] also rightfully claims that colours for the
different states have to be set, and also explains it in detail in
"Building Accessible Web Sites".
