Where did you get the impression that Erowid's prevoius name was hyperreal.org?
I thought Erowid was the project of Earth Erowid and Fire Erowid, who founded it in 1995: [1] [2]
From [2]:
"Erowid was founded in October 1995 by Fire and Earth Erowid. The site was a part-time project until October 1999 when it became large enough for Fire to begin working on it full-time. Earth joined her working full-time in March 2000. The site was run as a non-commercial business through 2007. As of January 2008, operation of the site was taken over by the newly formed non-profit Erowid Center. Erowid Center now has four primary staff members, two part-time staff, and dozens of valuable volunteers who help process incoming data, seek out new resources, and/or help keep the site up-to-date."
