But really, you should. The New Statesman New Media site has a report of a Tim Berners-Lee speech in which he says:
"The whole value-added of the web is serendipitous reuse..."Again, if you've heard the term 'semantic web' before, this will strike you as a clever (if ungrammatical) thing to say. But if you aren't, it will probably sound a bit pseudy.
My mate Ben reckons that this (old) article is still the best he's seen on the subject. Read it. It's worth knowing about.
(Modesty should forbid me from linking to the New Statesman New Media Awards judging panel, so I won't).
