Remember the era of e-everything? E-commerce spawned e-retailing (or the dreadful e-tailing), e-trading (E-Trade once sent us a cease-and-desist order for using its trademark), e-vangelism and a rash of e-spinoffs. Add to that rogues' gallery the overarching theme of "e-transformation," which we put forth in a cover story that, in hindsight, was a paean to the irrational exuberance of the time. It was the Enron era. Emerging "e-marketplaces" promised to change the face of industries -- Enron in energy and telecom, Covisint in autos, Elemica in chemicals and RosettaNet in electronic components -- vowing to connect buyers with sellers in real-time bliss. E-marketplaces fizzled, and most of the companies went bust or morphed into more conventional supply-chain management vendors or standards bodies.
