Jakob Nielsen occasionally drifts into utopian usability fantasies in which he tries to convince us that we should all stop using Flash and Photoshop. On the other hand, he occasionally publishes ideas that are valid.
I recently browsed a year-old article on Interaction Elasticity that contained this:
A path with 5 easy clicks is vastly superior to one with 3 difficult clicks. And a menu with 10 easily understood items is better than a menu with 7 obscure ones.
To put this in context, I was debating the use of a dreaded drop-down menu when I came across said article. For me, Nielsen's quote argued against things like drop-down menus, since providing a clear logical navigation path to subpages (even with 2 to 3 clicks) would be usable, clean and better for information architecture.
