When in doubt, tab, tab, and tab again

A lot of sites end up using tabs as a visual crutch when they don’t know what else to do with their IA. Take, for instance, earlier iterations of Amazon.com, which had a maddening array of tabs across the top until they finally collapsed them into the left-hand column.

But when you have three (count ‘em - three) sets of tabs across the top of your site, it’s time to take your architecture out back and shoot it.
