Here are issue against "Web of Data" :

1.  most people assumed a Web of Data from the onset of the Web
2.  the fact that a document may or may not host structured data doesn't 
invalidate it as a "unit of data" albeit compound in nature (re. innards).

Thus, based on the items above, whether its a Web of Documents or a Web 
of Data, we don't end up with immediate clarity re. what the new Web 
interaction dimension is all about.

I use Web of Linked Data because its easy for juxtaposition re. Web of 
Documents or Web of Data since neither convey implicit linkage of the 
kind delivered by generic HTTP URIs :-)
