standard flash nav in my opinion is a column on the left side of the browser window, very similar to 'standard navigation'. I think navigation depends on the use of a site. For something informative, a standard navbar should be used, people are used to the standard so why not change this in flash? They can understand it more easily and quicker because they have seen the 'same kind of thing' before. I think creative sites (www.Yugop.com is a prime example) can basically do what they like. The naviagtion here is simply radio buttons. Plain, simple yet innovative and effective.
