Yet the Web has a vast sub-terrain, a dark realm that is home to aggressive and destructive tendencies. Freud’s iceberg metaphor (1957b [1915]), which highlights the enormity of the unconscious in comparison to the conscious mind, can be applied to the Deep Web, which far exceeds the surface Web, and which in some ways confirms the pessimism embodied in Civilization and its Discontents (Freud, 1961b [1930]). Google, the largest search engine on the Internet, indexes a mere 0.004 percent of the surface Web (Jasra, 2010) and misses all of the Deep Web, approximately 500 times the size of what we know as the World Wide Web (Beckett, 2009). In other words, Google misses 99 percent of the World Wide Web’s data!
