In his latest blog post, Mathew Ingram writes about Paul Miller's interview with Sir Tim Berners-Lee, inventor of the World Wide Web. Miller's interview writeup is very interesting - as Marshall Kirkpatrick notes on the ReadWriteWeb, Sir Tim feels that all the pieces for the Semantic Web are already in place to realize a large part of the dream and to allow us to create applications that leverage the power of structured data and the integration of that data.
[One big problem for the Semantic Web that I've written about recently is the lack of meaning-enabled authoring tools; however, in the interview, Sir Tim indicates that this need is less critical; the structured data we need can come from databases.]
Coming back to Ingram's post, he says that the biggest problem with the Semantic Web is that "it’s as boring as dry toast" - i.e. it's all about the technical side, with discussions about plumbing and widgets and standards, and there's nothing there that will make people sit up and take notice.
