an astute article. One thing not addressed here is the failure of the Smantic Web paradigm to really take off; I don't know whether this is because of a lack of critical mass in the quantity of semantically coded data or the immaturity of ontology frameworks or something else - my best guess being that the browser is no more suitable to traversal of the semantic web than FTP/ Archie/ Veronica/ Gopher were suitable browsing tools for hyperterxt - although each solved 'part of the puzzle.'
