Nicholas Carr weighs in on the serendipity May 19 2006
Nicholas Carr weighs in on the serendipity of the web: "Once you create an engine - a machine - to produce serendipity, you destroy the essence of serendipity. It becomes something expected rather than something unexpected. Looking for serendipity? Just follow these easy links!" Previously on serendipity and the web: William McKeen and Steven Johnson.
Update: Steven Johnson responds to Nicholas Carr's post. The circle of feedback continues.
