Too much choice isn't a good thing. Many site designers obviously believe that if a few choices are good, a tremendous number of choices is even better. So their pages are cluttered with dozens of buttons, pull-down menus and other devices, with no clear indication of what choices are the most important or useful. Take a look at the ZDNet home page if you want to be overwhelmed with choices. Mario Garcia suggests that less is more when it comes to such choices.
Style remains important.
Every site should have a coherent, consistent style from page to page. While different parts of the site may cry out for different designs, some common elements are necessary for unity. User feedback is essential. Web designers often forget that what pleases them may not please normal people. So users should be sought out to test navigation and features and make sure icons communicate what they are supposed to.
