I just spotted a nice Semantic Desktop animation Courtesy of John Breslin.

This is fundamentally an animation demonstrating Semantic Web exploitation in the classic: picture speaks a thousand words manner. It also illustrates (yet again) the important Data Space(s) aspect of creating Semantic Web presence.

Finally, the Web 2.0 usage pattern tries to espouse what's demonstrated in this animation via data-context-challenged interactions (due to its "Walled Garden" and "Data Silo" approach to Data Access etc..). The Semantic Web (as per numerous posts on the subject) on the other hand achieves this via data-context-aware interactions (as will be exemplified via meshups).
