Response to this comment and "Knowledge as the next 'Next Intel Inside'" from Tim Finin.
As described in this comment, web 2.0 should make applicaitons understand each other. Is it too fast for the Web to develop at the current stage? Borrowing the comments from Tim Finin in his Knowledge as the next 'Next Intel Inside', with RDF data standards was fully recommended above XML/XSLT within the Web 2.0 era, the semantics between the applications could be built up, since then the real "understanding" between the applications could be stated.
This is purely my personal view point. Welcome all kinds of comments!
