Possibly of more interest to old school Extropians, you may be aware the defunct Extropy Institute's website is very slow and broken, and certainly inaccessible to newcomers.
Anyhow, I have recently pieced together most of the early publications, 1988 - 1996 of 'Extropy: Vaccine For Future Shock' later, Extropy: Journal of Transhumanist Thought, as a part of mapping the history of Extropianism.
You'll find some really interesting very early articles on neural augmentation, transhumanism, libertarianism, AI (featuring Eliezer), radical economics (featuring Robin Hanson of course) and even decentralised payment systems.
Along with the ExI mailing list which is not yet wikified, it provides a great insight into early radical technological thinking, an era mostly known for the early hacker movement.
