The day the metaphor flipped.

For years, I've been accustomed to the idea that websites have "pages" and blogs are "journals," and all the various manifestations of the metaphor of website as book. Yesterday, in the bookstore, I had the overwhelming sense that the books felt like websites. All those book covers were like the entry pages of websites, designed to get you to stop, hoping to draw you in and get you to spend some time inside. Were we really to buy these things and proceed through them front-to-back? Or do we pick them up and flip (click) around, with the most successful ones being sticky enough to get us to stay for an hour or so, and most of them, holding us for only a few seconds before we scan about for the next thing to give a instant's chance?
