No one pops out of the womb thinking in Boolean terms.In fact, surfing the Web contributes to an attention span so short that it precludes thinking of any sort. (Uh…hmmm, now where was I? Oh, yeah…) No matter how hard you try, you will never get that site design just right. The amount of real feedback from customers and potential customers is minuscule compared to the number of users and general traffic. All your bright ideas about increasing interactivity have become entries in that great Web dictionary in the sky under the definition of “broken link.” These realities make life miserable for site designers and the people who fund them.
