Manu,

Here is example of how we RDFize Digg:
http://tinyurl.com/3jtysp

The current RDFizer Cartridge somehow omits the sioc:Space nature of 
digg.com and the various sioc:Forums (which you pick up nicely above). 
I'll have our omissions fixed so that we have a complete RDF based graph 
of Digg which should ultimately aid RDFa renditions of the original 
(X)HTML resources from Digg.
