By simply clicking in, one could peer in on an unsuspecting subject. A forgery illuminates the nature of authenticity. When specialists at NASA interact with a telerobotic system, they are acting within a system of authority that gives them confidence about the reality of the system. Similarly when viewers watch live TV news broadcasts. But on the net, it is much harder to establish a corresponding authority.
Any determined teenager can set up a live web camera or telerobotic site.
Indeed, this lack of centralized authority is one of the net's primary advantages. The most interesting sites are deliberately ambiguous, intermingling false clues with distorted truths to motivate further exploration. I do not intend carnal knowledge in the Biblical sense although the two meanings are not unrelated. Perhaps not to the majority of casual net surfers, but to those who spend enough time to care, to patiently interact with a purported telerobotic site, discovering the site to be a forgery can be as traumatic as the discovery by a museum curator of a forgery among one of the Rembrandts in the permanent collection.
