Web icons don't die, they just get auctioned away.
Forget e-Bay. Auctions for dot-com bombs are 2001's premier flea market events.
What's more, souvenirs emblazoned with deceased e-trepeneur logos like Webvan, Kozmo and Pets.com have become hot new advertising collectibles.
There's a fellow in Virginia [1] who's turned buying up bright orange scooters from kaput delivery service Kozmo into a more profitable enterprise than Kozmo ever was.
Of course, it could be argued that aside from their logos, most e-failures were just wannabe brands. You be the judge [2].
