Though Yahoo has done some great things both aesthetically and technically to make their homepage one of the premier portals on the web, they can’t manage to redirect http://www.news.yahoo.com to point toward http://news.yahoo.com?

Why hand out an error page when you can send a user directly toward where you obviously know they intend to go?

The competition doesn’t have a problem getting it right (http://www.news.google.com), and to be fair Yahoo does give a helpful error page that steers the user in the right direction, but why not take them where they want to go seamlessly at the server level, DNS style? C’mon Yahoo this is basic usability, how many millions are on your doorstep every day? You should be laying out the red carpet, not setting tripwires.
