I'd like to agree with tbl, but I have a nagging feeling that semantic web is a bit like Ted Nelson's ideas for Xanadu: somehow too neat and tidy, wheras the web has been successful despite that. At internet scale the semantic graph is going to have to emerge from automated, deductive effort. There aren't enough people, and there isn't enough human attention or appropriate reward systems, to bring about a widespread semantic web by building metadata librarian-style. I wish it were otherwise.
