Timely reality check from Nick Bradbury (FeedDemon creator)
Apparently, Web 3.0 is the latest re-branding of the Semantic Web, a noble attempt to turn the Web of documents into a Web of data. Don't get me wrong - the goals of the Semantic Web are good ones, and I believe many of those goals will be met in my lifetime. But too much of the Semantic Web relies on data being valid - that is, valid XML, XHTML, RDF, etc. - and too many of us will never publish valid data.
