Excerpt from a timely hypertext reality check; read the full post
The nub of Carr’s argument is that every link in a text imposes “a little cognitive load” that makes reading less efficient. Each link forces us to ask, “Should I click?” As a result, Carr wrote in the “delinkification” post, “People who read hypertext comprehend and learn less, studies show, than those who read the same material in printed form.”
This appearance of the word “hypertext” is a tipoff to one of the big problems with Carr’s argument: it mixes up two quite different visions of linking.
“Hypertext” is the term invented by Ted Nelson in 1965 to describe text that, unlike traditional linear writing, spreads out in a network of nodes and links. Nelson’s idea hearkened back to Vannevar Bush’s celebrated “As We May Think,” paralleled Douglas Engelbart’s pioneering work on networked knowledge systems, and looked forward to today’s Web.
