www.theattackof911.com, http://www.guesswhodidit.com. These are just some of the URLs born on Sept. 11. While most people spent that morning paralyzed by horror, others snapped up Web site names related to the events. BulkRegister, a domain name registrar headquartered in Balti-more, received at least 200 requests within 20 minutes of the first attack. From www.freedomwillprevail.com to www.wherethehellwassuperman.com, names reflected reactions to the events, said Tom Cunningham, CEO and founder. “There are some expressing anger, some trying to help, others selling T-shirts…. It reflects human nature. All within an hour.”
