Several weeks ago Amazon.com revamped its navigation, and I like it. Rather than tab Hell at the top, there's Amazon.com, [Your Name]'s Store, See All 31 Categories -- and that's it.
Amazon used to offer a small set of tabs and then "everything else." I always found that aggravating because the tabs I used (I'm a DVDs, Books, and Electronics person) were sometimes hidden. So the company appeared to make my life easier but didn't. At least with the 31 hidden tabs its clear that I get to chose, rather than be penalized for going to an upopular tab.
Besides the new tab behavior, the page is generally less cluttered. And when you type a query into the search box, your typing appears in BIG LETTERS. As a person aged 50+ whose sight is failing, I like that feature.
Once again, the above changes show they're always thinking at Amazon. Now if only most other Web sites would do the same.
