Web's limitations as a medium for publishing newspapers' content

A post on MeFi points to an article on ZDNet which offers an analysis of some of the web's limitations as a medium for publishing newspapers' content.

It focuses on NewsStand, the service offering the NYTimes, the International Herald Tribune and others in PDF format, and says some interesting things about the respective formats' ease of use and ability to guide readers to what they're looking for. (It has me thinking, is HTML/CSS just too limited to do certain things well?)
