I first learned of Ted Nelson’s Xanadu vision from his 1974 book Dream Machines, one-half of a dual book with Computer Lib, and in the later (1981) Literary Machines. I don’t recall when I read these.
Eventually I realized that Nelson wasn’t getting anything into production, and started to fiddle with the idea of implementing something similar myself. I tentatively called my approach XinX. This was based on the cute notion of a recursive acronym, and stood for “XinX is not Xanadu”.
It’s a long shot that I will ever devote much effort on this project, but Nelson’s vision of a hypertext/hypermedia system still has a lot appeal for me. In addition to being a meme, it should support some interesting applications of memetics.
