Hi Kingsley,
I have a few questions. See below.

Then you go on to say that it would be much better if it said:
"id": "https://www.facebook.com/kidehen#this";
For the record, after scratching my head a few times following responses from
both Richard and Glenn re. item above, I now see that really meant to have
posted:
https://graph.facebook.com/kidehen#this
Would you agree that Facebook are the owners of this URI?
I would say they own the URI: https://graph.facebook.com/kidehen
I use that URI as the basis for a disambiguated URI in my data space,
for instance, as per my comments re. owl:sameAs relations in my data space.
Would you agree that the owner of a URI gets to decide what it identifies?
Of course.
Would you agree that a good URI is one where the URI owner has explicitly
communicated (ideally through its representations) what it identifies?
Of course.
If I wanted to state, using Facebook URIs, that I know you, would you expect me
to do this:
<http://graph.facebook.com/richard.cyganiak#this>
foaf:knows<http://graph.facebook.com/kidehen#this>.
In a graph, in my data space, it would be meaningful and useful since I
would have triples in place that provide additional information about
the referents of the identifiers in the relation above. Outside my data
space all bets are off.
or this:
<http://graph.facebook.com/richard.cyganiak>
foaf:knows<http://graph.facebook.com/kidehen>.
Not in my data space (bar you having CRUD privileges there), of course
you could make that assertion in yours :-)
My data space is a place where I control data CRUD operations. Its also
a place where inference rules are optionally associated with SPARQL
queries, for instance.

Thanks,

And yes, that's owl:sameAs:
https://graph.facebook.com/605980750#this .
Re. this whole matter of Names and Address ambiguity relative to usefulness,
Facebook doesn't really grok the above, neither does it grok fact that:
<https://graph.facebook.com/130118787030077#this>
owl:sameAs<https://www.facebook.com/kidehen#this>,<https://graph.facebook.com/605980750#this>
.
Instead of burning cycles getting them to think along the lines above, best I
get something made that takes advantage of this insight for the time being :-)
