I've been thinking for a long time about the structure of the newspaper, how the physical depth and the page layout - the careful placement of photos, headlines, graphics and stories - draw readers' eyes to information they weren't looking for, allowing for connections and discoveries to be made.
Cass Sunstein, a professor of law and political science at the University of Chicago, calls this the architecture of serendipity. Thus far, most blogs and Web sites fail to provide this dynamic interplay of ideas. Their convenience makes them less interactive. They are flat.
If the physical newspaper is to die, or diminish, I hope news organizations spend some money trying to recreate - even enhance - this alchemy online, rather than settle for the cheapest recipe and the easiest delivery system.
