Some consistent themes in Steve Krug's writings in Don't Make Me Think include putting up as much information as needed but no more, be concise, be clear, and always let the user know where they are. In Assignment 6 and in the Bio page the navigation is only on one level. So a simple background chang in the links is sufficient to alert the user without the need for superfluous and confusing instruction. Less is more. But I did leave the name of the story on top of all the pages of assignment 6 to remind the user where he is.
Navigation was made standard (more or less) by putting a horizontal bar near the top of the page under the website logo (story name) with the chapter numbers as the destinations. On the first page, which is a title page, the title, author name, a picture from the story (with caption) were included to help explain quickly what the website was about. On all the subsequent pages the link (with a unique rainbow background) and the page title (chapter number) matched to help confirm that the user has arrived where he is attemping to go to.
Later I would like to use the tab layout for linked pages because I agree that it was the most effective way to let the user know where they were. Besides I think they were cool.
The individual paragraphs were separated in the story to increase readability and to help the reader track who was speaking. I use the pre-line attribute so I could format the body in a text editor(easier and less distracting).
The most important thing I did was not clutter up the pages.
