Abstract:

Half of knowing where you're going is knowing where you are. So a fundamental part of creating a great web is to let your readers know where they are at all times. One way, of course, is to use tabs and menus that literally tell them where they are. Here at ideabook.com, for example, you know where you are by looking at the top of the page–-the tab tells you you're in the 'DESIGN PALETTES' section and the headline tells you the article title.
