Form Follows Function...Follows the Web

I'm probably slow getting to this, and doubtless this has been blogged already, but I noticed in today's Financial pages of The Guardian (I've noticed a few things in its hallowed pages today) that the article "bulking up in the drugs industry" contained blue, underlined keywords which were then further defined in a call-out box. I think it's really interesting that a print publication is using the default hyperlink formatting to indicate "more information" - the influence of the WWW continues to grow.
