Clay Shirky in the Echo Project wiki's "project motivation" discussion:
Almost nothing of what [Ted] Nelson imagined has come to pass. He was wrong about transclusion, wrong about stateful conversations, wrong about how to handle unique IDs, and almost everything that [Tim] Berners-Lee did right -- limited semantics in the application protocol; made it stateless; and created the 404 error, living embodiment of worse is better and savior of scale -- violated Nelson's bankrupt vision. Xanadu was the wrong answer, REST (Representational State Transfer) is the right one. If you thought that all that was wrong with RSS 1.0 is that RDF didn't make it confusing enough, attach the twin boat-anchors of OWL and the Semantic Web to Echo and see what happens.
