Tim O’Reilly, who framed the concept Web 2.0, sees a new development for the Internet “The Web is no longer a collection of static pages of HTML that describes something in the world. Increasingly, the Web is the world: everything and everyone in the digital world casts an “information shadow,” an aura of data which, when captured and processed intelligently, offers extraordinary opportunities and mind-bending implications.”
On the other hand “as more of the unstructured information that we create (or that is created about us) is retained, our digital universe expands and our own digital shadow lengthens”, reports Mark Lewis from IDC, a US-based ICT market intelligence service provider.
