“Elvis had a ghost brother, Aron — a twin who died in childbirth. Elvis grew up to be the king of rock and roll. Nobody knows what Aron Presley might have become. The Web is similarly populated with the ghosts of the unborn. For every site we visit, there are undoubtedly better-designed versions that the client rejected and we will never see. If there’s a rock and roll heaven, perhaps there’s one for unborn Web sites as well.”
