This seems to mostly be about Xanadu, which I've heard of in passing before but never really looked into. Some of the features sound nice (version control, content-addressing), some are confusing or undesirable (some mechanism to avoid sharing copyright-protected content?, backlinking, micropayments?). The screenshots of what I presume are Xanadu browsing in action look more like schizophrenic corkboarding than a useful document format, with the emphasis placed more on tracing the provenance of summarized or quoted text than on presenting something readable. Perhaps this style comes more naturally to one more familiar with working in academia and reading/writing papers in that sphere. Being a document distribution system, I don't think Xanadu competes with or is even in the same category as The Web, which as we all know, is an application distribution platform and runtime first and foremost.
