Currently FreeBase, FreshBooks, FeedBurner/FeedBulletin, ...
And anyone in the world who comes up with a F*B* in a future product.
It should probably be mentioned but OpenGraph actually doesn't use RDFa

some things like og:image:{secure_url,type,width,height}.
So it's really "syntax based on RDFa" rather than actually being RDFa.
