Francois,

Since the overall theme is Linked Data (HTTP URIs for data objects), how 
does WolframAlpha add any value if the end result is an opaque HTML 
resource (one that lacks structure data granularity or pointers to 
structured data sources)?

Value comes if Google exposes its Dataspace GUIDs as HTTP URIs, and then 
WolframAlpha (or anyone else in the data processing pipeline) does the 
same, then you get something that is truly valuable i.e.:

1. Computation Answer Engine that emits its Linked Data (as per Linked 
Data meme)
2. Google's contribution to the Linked Data Web realm via Data Spaces / 
Virtual Database technology that also emits Linked Data.

The ultimate value of the Web remains the fundamental separation of the 
following re. data:

1. Identity
2. Storage
3. Access
4. Representation
5. Presentation.

We cannot see, comprehend, and appreciate the Web via item #5 solely, 
which is always the case when the output representation from a Web 
service lacks pointers (HTTP URIs)  to  RDF model based structured and 
interlinked data  in line with Linked Data meme.

To conclude, things will more than likely get better now that  Google, 
Yahoo!, and Microsoft (naturally) are beginning to see alignment between 
their respective customer-driven technology adoption strategies and the 
virtues of Linked Data, thanks to RDFa and the GoodRelations vocabulary.
