The Wall Street Journal online edition has nearly 990,000 paying subscribers. So I can safely say it is something of a Web giant. But while the print edition is a well designed and smartly laid-out publication, the main page of the online edition lacks most of the design soundness and all of the panache of the print version. In fact, it’s a visual train wreck. But not for the big picture elements; this page fails badly because of simple details.
