We've had sponger meta cartridges [1] for the Guardian API since its 
early incarnations.

Anyone that uses URIBurner [2] ends up with a look-up pass through 
Guardians API (amongst a boat load of others) en route to the final 
URIBurner generated Linked Data graph. URIBurner then pings PTSW which 
ultimately leads to data in the LOD Cloud Cache we maintain.

Sindice also does URIBurner lookups, and URIBurner also looks up Sindice 
(sames.org  etc..) .

End result, dynamic Web of Linked Data. We stopped counting its size in 
2007 :-)

Of course, others too should make wrappers for these APIs so that their 
perspectives are expressed in the burgeoning Web of Linked Data etc..

On our part, we've been doing so since Linked Data inception, and will 
continue to do so :-)
