This is a great way to increase your social network, among SPARQL enthusiasts :-)

I get a

[[
virtuoso RDF02 Error SR619: SPARUL LOAD access denied: database user 178 (kidehen1) has no write permission on graph http://www.w3.org/People/Berners-Lee/card
]]

This is probably because I only just added 

 <http://id.myopenlink.net/dataspace/person/KingsleyUyiIdehen#this>;

to my profile, and you may have an older cached version of my profile in store. Btw. I used
to have <http://kingsley.idehen.name/dataspace/person/kidehen#this> . which one do you prefer, or
should one use both?

IF that is a problem it does bring up an interesting issue, namely one of up-to-datedness of
the store. The most efficient thing to do for this demo would be to do a Conditional GET on the
Webid Profile I suppose...
