Examples

Poor: Menu item for current page is active and indistinguishable from the rest. Good: highlights current page and is not an active link

Poor: multiple nested (cascading) roll down menus

Good: in dropdown menus make the top item link to an overview page that contains the other links too

Provide links in their appropriate context do not make people search in menus
