Aside from their more practical value, I've often thought that the Erowid experience vaults would make a great jumping off point for a short story collection or novel. There are so many memorable stories and voices buried in there (many quite sad, of course, but others that resemble a 21st century, anonymous version of gonzo journalism, like the witches doing intravaginal DMT or the hardy soul who combined crack and MDMA at Disney World).
