Kolb on Ziegler
Philosopher David Kolb (Socrates in the Labyrinth) has written a thorough, thoughtful, and devastating response to Henning Ziegler's When Hypertext Became Uncool.
Ziegler promises to give socio-political reasons for the phenomenon of rapid attraction and then rejection of utopian hypertext dreams. His essay does not actually give such an analysis except for general incantations about contradictions and the relation of freedom and constraint.
Kolb's rebuttal is gentle, scholarly, very generous, and conclusive.
