I've just done a few things:

1. Added a gr:BusinessEntity triples for both Apple and Google
2. Sponged the DBpedia hosted descriptions of both
3. Used the FILTER feature of Relfinder to remove seeAlso links from the 
mix .

When you refresh the URL above, I hope you see some aspect of what my 
initial response and euphoria was about re. progressively generated and 
enhances Linked Data Spaces.

More than anything else, in my world view, Linked Data is about:

1. Loose coupling of Information and Data
2. Ability to explore data relations through your own Context Lenses 
across their various dimensions.

The steps above reduce the cost of "Subjectivity" and "Myopia", two 
things that always benefit from Information bearing resources that don't 
provide routes to their data sources.
Remember, information is "data in context", and it's inherently 
subjective :-)

BTW - even if RelFinder only had seeAlso links, re. my original 
comments, don't you see how the graph exposes erstwhile invisible data 
or serendipitously unveils other relevant things (again very much 
dependent on the context of the beholder). In my case, I found the 
keynote-speakers node interesting (amongst others).
